I expect that proxies will in almost all cases employ standard 5222 TCP 
connections with the servers. But perhaps I'm missing something? IMO 
JEP-0124 will probably never be used for server-to-server communications. 
However, I certainly don't want to close down unnecessarily that (or any 
other) possibility.

The primary motivation for adding optional multi-streams was to allow a 
single constrained (Web) client to open several streams with a proxy 
(something that v1.4 of the JEP made impossible). For example, on weekdays a 
user might want their client to be logged in simultaneously via a proxy with 
these bare JIDs:
vinod at work.com
vinod at personal.com

At least one implementation of client/proxy multi-streams is already in
