Cisco are offering something jabber shaped as a service like this, and apparantly that works (i bet they wont tell us how or why though!). I really wouldn't mind paying a few pounds a month for a service like this, but not from them. Anyway - it is all over my head, but i guess all the info helps :)


this is usually a case of problems of NAT traversal. Jabber uses STUN [1] servers for that, IIRC. Essentially a Jabber server needs a little more setup to pass through WIFI access points et cetera for video chat.

Cheers, 

Mirko.
