First release ?? Really ??
Sounds like they've rebundled Groove which has spent so long being 'really here soon, honest', while being not actually what anyone wants, that I'm surprisd even Ray Ozzie is still interested.
Maybe it's the MS equivalent of vanity publishing - "yeah Ray, we're going to turn that into it's own .NET project for all the .NET dweebs (who can't write their own code bit only glue things together) to wet their pants over"
Ho hum, wake me up when some genuine tech comes along, as opposed to MS goons letting their boss beat them at golf...
