I recently received an invite to Google Wave (thanks Rory). From the few minutes I’ve played with it so far, it seems to be Google’s next offering in collaboration (Google Docs is probably their first). I’ve still got some spare invites, so send me an e-mail if you’re interested in trying it out.
One of my bosses from a previous company came across a couple of links that explain Google Wave:

http://lifehacker.com/5395376/the-complete-guide-to-google-wave-is-a-comprehensive-book-on-wave
I’ll probably be checking these out when I have time (if I’m not distracted by other “oooo shiny” toys, or life in general).
