The Nota web site offers up some examples of how their tool can be used, including a study notebook for school which could incorporate Wikipedia articles and photos; an online scrapbook, where you organize your online photos into a collage; or even a greeting card, where you and several friends can all collaboratively sign it, leaving messages for the recipient. They even recommend several ways in which Nota can be used for educational presentations, like class projects. Nota is especially useful for that as notebooks can be worked on by as many as 50 users.

Getting started with the service is simple, too. You just sign up for an account and click the "Create New Notebook" button. You can then give your notebook a title and set it as public or private. Just be careful when selecting that last option because there doesn't appear to be a way to go back and change it later.

When adding web content, it's easy to search by keyword or you can enter an account name in order to grab specific photos from sites like flickr, Facebook, or Picasa. Unfortunately, you don't have the option to do the same with YouTube - you have to search for the videos instead. When you find the content you're looking for, one click lets you add it to the page where it can be dragged around, resized, rotated, etc.

When you're finished with your creation, click the "Share" tab and you can post the page to Facebook, Blogger, or LiveJournal or you can grab the embed code to post it anywhere else on the web.

Over the years, we've seen a lot of tools that promise easy web page creation, but Nota is one that really delivers. It really is as easy to use as they say it is and that makes it fun to goof around with, we have to admit. Although we might be a bit older than the intended demographic for the product, it's easy to imagine how younger kids and teens would really get a kick out of using Nota for customizing their online profiles or for working on school projects.

Nota has been in private beta for several months now, but the veil just lifted yesterday. The service is now a public beta, which means anyone can try it.

But the real magic happens when two Whiteboard users come into close proximity of one another. Using the built-in wi-fi functionality, Whiteboard gives users the option to wirelessly tether two handsets together. The result? A collaborative sketchpad where users can draw on the same surface - even if they're across the room from one another.

Our expectations weren't high. We expected some lag between drawing on one surface and having it appear on the other iPhone. But we were pleasantly surprised. The app is incredibly responsive. Watching the drawings on one iPhone almost instantaneously replicated on the other user's screen is, if nothing else, entertaining. And entertainment is most likely going to be the most prevalent use.

Granted, using Whiteboard to sketch wireframes before your big client meeting or drawing a quick diagram of a process for your colleague are all perfectly reasonable and serious uses of the tool. But it's far more likely that - as fun as the app is to use - you'll find yourself using Whiteboard to engage in games of Tic-Tac-Toe and Dots & Boxes with colleagues during meetings.

Whiteboard is a free application. To try it, download it from the App Store or search for "Whiteboard: Collaborative Drawing" from the App Store on your iPhone.

With the new SynchroLive Communication platform, the service is now more scalable while keeping all live communications synchronized, no matter whether you're sharing audio, video, files, or web pages. This was one of the areas where Dimdim stumbled in the past. When we used it here at RWW for sharing our desktop with our readers during our testing of Chrome, the audio and video weren't matching up. That problem is, supposedly, no more. (We'll have to do another live demo and find out!) Says the company, the platform now makes it possible for five audio streams to be recorded, where before Dimdim only supported recording one.

The platform also allows for the new co-browsing feature to work. With this, a presenter can share their web browser with viewers who can then also be made presenters in order to browse along with the original presenter. The co-browsing allows for scrolling up and down, but does not track mouse movements, so it is not as good for using your mouse to point to an element of a web page. However, when you just want to share material on the web with a group - say, for example, a professor teaching remote students, it would be a good solution.

Open Source Dimdim, "Liberty"

Also launched today with the release of Dimdim 4.5 is the launch of "Liberty," the Open Source Community Edition of the new commercial hosted version. Liberty's complete source code will be made available under a GPL3 license with no limit to the number of attendees, meetings, or mashups that can be created. Liberty is also available as a downloadable VMWare Virtual Appliance.

The Open Source version also integrates with other web applications, including:

• Zimbra: Dimdim now offers a free zimlet for Zimbra's open source email system;
• Moodle: Dimdim is integrated with version 1.9 of Moodle's Course Management System;
• SugarCRM: Dimdim is integrated with the leading open source customer relationship management system,
• Claroline: Dimdim is embedded within with the collaborative learning environment.

More Enhancements

Those who have used Dimdim in the past will notice some subtle UI changes in the newest version including a smaller top frame and revamped menus on the left. Drop-down arrows have been added to those menus for easy access to files and shared web pages, too.

In the future, Dimdim will also allow for skinning changes and templates. Because Dimdim's service-oriented architecture is composed of a handful of different services (screen sharing, audio streaming, video, etc.), the platform makes it possible to use customize the look and feel of the Dimdim interface and create a template just for your needs. If you're only sharing web browsers, for example, you could turn all the other features off. The templates created by Dimdim users could then be shared with each other. Dimdim says these new features will be available sometime early next year.

In addition to the no-cost Open Source version, Dimdim will continue to offer a free version for meetings with 20 or fewer people. Dimdim Pro 4.5 starts at $99 per year for unlimited meetings plus video chat.
