Zimba: an ajax communication client

Via Jon Udell, here’s gmail on steroids: zimbra. Zimbra is a beta, but looks like it does all the things I wish gmail would let me do – online calendaring and contact management (which, to be fair, gmail handles OK already) all integrated into the one interface, much like Outlook. Nice to see as a next-generation online tool; personally I hope the guys at 37signals hook basecamp into it, then I’d be really happy! I also liked the little googlemaps mash-up for showing location. Makes you wonder what Google will do to push this on a bit further - will they develop gmail as an online client some more and try to match some of this zimbra functionality?
