At last, Microsoft is embracing open source, with a plugin for Moodle that lets subscribers to Microsoft's (already free) live@edu service use a single sign-in to access both Moodle and the live@edu tools.
Why?! Has Microsoft suddenly changed its business model?
No. Consider some other explanations: Moodle is an open-source Virtual Learning Environment (VLE) already in use in schools across the world (over 2 million installations, last time I checked).
Earlier this year, Google collaborated with Moodle to offer a single sign-in to Google Apps.
So, Microsoft's move, in this context, is reactionary. Both companies are engaged in a battle for the hearts and minds of the next generation of computer users. Indeed, for years, Microsoft has offered its software products to students at hugely discounted prices, to "indoctrinate" them in the use of Microsoft tools.
Cynical? You betcha.
