Here is the simple criteria I am using: 1. Must use gtalk 2. Must have persistant history for at least 48 hours (searchable is a bonus) 3. Must be accessible from adium or other chat clients 4. Must be private for our org.

So far I have identified, Jaconda, hipchat and campfire (although I think it is out due to the lake of gtalk integration)
