Shouldn't multi-stream support go into a separate JEP?  This could be
used on both ends of a JEP-0124 implementation.  Eg. an HTTP client
using multiple streams to a JEP-0124 server, and the JEP-0124 server
using a single tcp connection with multiple streams to an xmpp server.

Great!  This widens the scope for JEP-0124 implementations.
