New feature wouldn't be supported at all, as practice shown: there were 
XEP about sessions handoffs, now, who can recall it's number?

Such scaling is not a way to go: balancing doesn't help you to much 
until you have too many *shared* data across a cluster. A good approach 
is taken by SIP folks: they put some pieces of state in packets using 
record-routing technics and this works very good.
