XMPP already is highly popular -- I estimate 10+ million IM users. And
so far the network usage is by no means extreme: on average, probably
about 15 bits/second for every connected user, so that a server with 
1,000 concurrent users would consume about 15 kbs of bandwidth, 10k 
users would consume 150 kbs, etc.

I'm still not convinced there is a problem with the XMPP specs as they
are today. However, in certain situations, extended addressing (as in
JEP-0033) might be helpful.
