According to wikipedia, skype had 443 M users and 42 M active (daily presence) in Q1 2009. Some people claim to have 250,000 users on one OpenFire server (xmpp), and 20,000 users for Asterisk (SIP). I don't think scalability will be an issue, especially with open protocols, in the end you can expect the same organisations running mail servers today, running sip/xmpp servers tomorrow, with roughly the same number of users. Remember that you only talk to the server during the time it take to establish the peer to peer connection, and no payload goes to the server (at least not for video and audio), so there is very little load on the server. The other advantage of a server based solution to establish the call is that you might not always use the same device. I use an xmpp client sometimes on my desktop, sometimes on my laptop, sometimes on my phone, sometimes on a completely different computer, either installing a thick client on it, or using a web service... -- Yves. http://www.SollerS.ca/ gmail, jabber, LiveJournal, nimbuzz, ovi, dreamhost xim.ca: xmpp:y...@zioup.com _______________________________________________ Discuss mailing list Discuss@lopsa.org http://lopsa.org/cgi-bin/mailman/listinfo/discuss This list provided by the League of Professional System Administrators http://lopsa.org/
