If ever there was a company I want to root for it's Jive. This little company is churning out some great product right now and the most recent developments in their collaborative tool Clearspace make me think this support is not unfounded.
This tool is a light weight wiki/DMS/IM platform that plugs in beautifully with their open source XMPP (GTalk/Jabber if you aren't hip on the lingo) offering - Openfire. It also has plugins to connect to all those nasty proprietary networks as well (MSN, Yahoo, etc).
The applications themselves are well designed, have very clean UI and the admin console is very shiny and usable. The bonus to all of this: they just work. By using clever engineering and good architecture this platform combination will run on practically every Java supporting host known to business. I like that.
In addition the integration of the IM piece with the collaboration piece is well thought out and seamless. You can see who is where and if they are available... presence to the N'th degree here folks.
And it's cheap. Free for less than 5 people and 29$ (US) a year/user for more.
If you have the time/inclination - check it out! You will not be disappointed.
