Well, that's basically the same level of protection (and method. more 
or less) as I proposed with adding an extra ID, expect it doesn't 
protect multiple accounts on the same server (also it doesn't protect 
any other application that would use sha1(userPassword+serverHostName) 
for storing passwords, maybe we could make it 
sha1("xmpp"+userPassword+serverHostName) to address that). 

At least it's a whole lot better then the original proposal, since this 
solves, and considering that my proposal includes sending 1 extra key 
this would be the easiest to implement in excisting clients. The 
problem is with domainaliasses though I think. I'm not sure how these 
are used exactly in Jabber. Is it possible to use the same user 
database for two different domains?
