If you have to jointly author a spreadsheet with a colleague, what is the first thing that you do? Email it back and forth. This can be painful, particularly as you try to keep track of your partner's changes and hope the emails transit back and forth across the Internet. Add a third or fourth person, and things get worse. Luckily, there is a better way, and a number of Web-based service providers have stepped up with tools to make spreadsheet sharing a lot easier than sending attachments.

We've written about a few of them, including Longjump and Hyperbase (one of our products of the year for 2008), but I have tried a bunch others, and will show you what is involved and how they stack up.

DreamFactory's suite of Enterprise 2.0 applications consists of a Project Management module, a Time and Expense Module, a Document Manager, and a Team Calendar. (See our coverage of their launch here). Originally, the company was available on Amazon Web Services, but it looks like they aren't interested in being tied to just one platform. As of today, DreamFactory's software will be available on Intuit's QuickBase platform, which makes it the fourth platform for DreamFactory's suite.
