Deeje Cooley points to a press release from 21 Publish announcing that they are releasing an OEM service that allows licensees to create private communities of interconnected blogs.

While the details are a bit sparse (and I've yet had a chance to play with it -- having loads of fun quasi learning CSS and PHP this weekend...), this could be a very powerful concept for businesses, potentially letting companies like Intel, Cisco et al manifest their partner ecosystems in blogs, RSS feeds, etc.

Certainly something to watch...
