I was wondering about this a few days ago also. With the central JUD 
at jabber.org, it is very easy to get valid jid for quite a few 
people ... And I think, as soon as jabber get a certain marketshare, 
spammers will discover this network. I already received a few 
'unwanted' messages.

I think, the first 'solution' would be a start, and with some limits 
on how many auth request per time... Still one could think of ways 
surpassing such limits.
