Leading virtualization company VMware announced today that it's acquiring SpringSource for $326 million in cash, plus another $58 million worth of stock and options. SpringSource will retain its executives and become a division within VMware.

SpringSource is used in many top companies to manage the full lifecycle for Java applications in the enterprise, on the Web, and in enterprise integration. The purchase merges VMware's focus on infrastructure with SpringSource's expertise when it comes to enterprise application and rich Web development. For VMware, it's the beginning of a complete platform as a service offering for Java.

MindTouch — the open source, wiki-based intranet — is the first software to bring fully collaborative video to the enterprise. The new feature comes from open source video platform Kaltura, which is also developing video editing for Wikipedia. Through Kaltura, MindTouch customers will be able to cooperatively edit, publish and syndicate video both inside and outside the firewall, all with a complete revision history.

In addition to collaborative video editing, users can now package their applications and content for reuse on other installations. Developers will be able create open source add-ons that operate just like those in Firefox, and anyone can use a desktop GUI to select content for staging and migration.

In little more than a month, the beta of Appcelerator's Titanium Mobile has garnered the attention of more than 3,000 developers. But the beta hasn't just gotten some respectable use: it's changing what kind of apps get created.

Titanium Mobile is aimed at those looking to build apps for the iPhone and Android, but who'd rather code in standard HTML, CSS and JavaScript instead of Objective-C or Java. By opening up the most popular mobile devices to anyone with Web development chops, an entirely different class of app has taken over on the platform, compared to what you'll commonly see in the App Store.

Facebook announced a major change today to the proprietary language that all Facebook apps are written in; it will now be made extensible with custom tags that can be shared across applications. The feature will initially be available only on site but will eventually be rolled out to all Facebook Connect supporting sites around the web. We're excited about it but wonder how open it will truly be.

FBML, or Facebook Markup Language as it's called, was intended to ensure that malicious apps couldn't inject nasty code into the browsers of users. We assume that the new markup will have security taken care of by server side processing and this could enable an explosion in feature sharing and code efficiency.
