Microsoft Office Groove 2007, all I say is WOW. Wednesday, April 11th, 2007
Groove 2007 allows you to create ad-hoc virtual teams to work on projects.
It uses p2p type technology to keep everyone in the team in sync and does other things like instant messaging, push to talk (to the virtual team) and lots, lots more.
I am going to do a demo Screencast about it, its going to be easier to demo than write about.
