I'm really interested in this as well.
One of the main requests we've been getting this week is when are we going to have a mobile version of www.LiveBaseballChat.com <http://www.livebaseballchat.com/> Regards, [email protected] ________________________________ From: [email protected] [mailto:[email protected]] On Behalf Of Thiranjith .

From what I understand, phones' end-point IP changes as they move around, and generally they are behind the network operator's (At&T, Vodafone etc) firewall. Say that user 'A' sends a message to our mobile client. From what I understand, the message will go through the XMPP server (e.g. Jabber.org or our own) to find where our client is, so it can route the message. How would the XMPP server know where to find our client in the place? The IP our client used when registering with the server could be different now because it could have moved around. Does the mobile client need to periodically notify the server about its IP? From what I understand, the BOSH technique described in http://xmpp.org/extensions/xep-0124.html#intro is meant to address this, but it seems to work only if the entity behind the firewall initiate the connection first (in this case, the client running within the mobile phone). Please correct me if I got all this wrong as I am new to XMPP, but I would greately appreciate if anyone can explain how the xmpp server finds the mobile client that is on the move. Does our sever needs to implement that routing logic ourselves? Any articles explaining this would also be great! Thank you! Thira
