well, this is a fact of life in Jabber, if you want to send some  
information you'll have overhead of namespaces, wrappers, etc. In this  
case the rate of information updates is simply higher than with sending  
"complete" messages. For cases in which this is worth it (for example  
TEXTphone style applications for the blind) there is nothing wrong with  
this. You can always strike a balance in the update frequency if bandwith  
is a really big issue.

I think if bandwith is this important to you though, it's better to look  
into stream compression methods than to dismiss jabber as a protocol. It's  
exactly this kind of repetative data that would compress well.
