Poor you! The way it works is such a mess in 2.0.6! The high level of
"socket identity" has to bubble down to the lowest possible level
(encoder/decoder). It's really ugly.
However, with help of others on the mailing list we've devised a concept
of "multi-part messages" which will solve the problem in elegant fashion
in 2.0.7: Simply send the identity as a separate "message part" rather
than as message prefix. All is done in xrep_t class. Session, engine,
encoder, decoder etc. can be completely ignorant of the functionality.

Wow! First time I see the whole thing in a single diagram.
