I'm looking into installing a Video/Audio/Chat collaboration solution exclusively for users on my network, and those with valid Active Directory credentials. I do have a mix of Mac & Windows users so ideally something XMPP compliant will be best. This should allow me to video conference, share files, and even present and should have an after-effect of reducing the utilization of our mail server for communications that may not necessarily need to be stored and archived...
I'm wondering who out there has had experience with the various XMPP Solutions out there and if they would recommend one over the other... I have already tried Mac OS X's implementation of Jabber which was a failure so perhaps a Windows based solution will more easily interface with my Active Directory. All of my macs will be using iChat as their client software but I haven't yet established which client the PC's will use.
I've begun looking into openfire but didn't want to get too far into research if there were some strong opinions out there.
