You still need to resolve conflicts for any global table if you want to
be partition tolerant. I really see no benefits. Also sometimes you
need to fetch some info about a connection (like an IP address), but if
you keep only {jid -> resources} global mapping you need to perform RPC
calls to other nodes which is expensive as hell (in terms of latency).
