It's a problem indeed. Google Talk is one such client which doesn't  
allow you to set a priority nor a resource, yet never causes  
conflicts (which is the way it should be IMO). The Google Talk server  
sends all messages to a bare jid to *all* connected instances with  
the highest priority, which i think is the way to go. (In fact, they  
send it to clients with a higher resource as well, but although it is  
allowed, i'm not really fond of that behavior). Unfortunately, you  
can't rely on this rule, as the XMPP spec allows the server to choose  
any delivery rule for clients with the same priority.
