That's exactly my point: XMPP 1.0 is good for desktop clients, and at
present for a series of reasons I've already talked about I prefer
BOSH for mobiles, but an extensible binary xml protocol would be the
best of both worlds.

One more good reason for using BOSH with mobiles: you can fix very
quickly the binary data issue offering the decoded, more compact, data
on the same channel, accessing it using a different path in the
request. The change would be almost trivial, leaving the time for a
decent binary XMPP 2.0
