[JDEV] Jabber and XML compression

There's been plenty of discussion on this in path, see:

  http://mailman.jabber.org/pipermail/jdev/2002-January/thread.html

(it seems the threading got a bit broken - search for "GZipping Jabber
Messages").

The outcome of this discussion seems to be that yes, you can compress
the stream, but the gains (less bandwidth usage) don't necessarily
justify the costs (higher memory and CPU usage, and more complex
implementations).

Having said that, its worth noting that more and more servers and
clients are using SSL, which compresses data (and you get encryption for
free).
