The design of jabber module was to act as a Jabber client for each SIP 
user, the new module acts as a XMPP server or as a XMPP component (if 
used with stand alone XMPP server).

This new module uses only one connection to any XMPP server, while the 
old Jabber module uses one per user, which does not scale. The jabber 
module is more for connecting to other IM networks (like icq) via a 
jabber server, and required to have a Jabber account for each SIP user, 
and will stay so.

The XMPP module is simple oriented to XMPP and latest RFC/drafts which 
removes lot of restrictions and constraints (like bounding a sip address 
to a jabber account). Following the latest XMPP RFCs we could implement 
server to server communication in a easy manner, improving the 
scalability a lot.

Having everything in one module would result in something very heavy and 
hard to maintain.

Cheers,
Daniel
