"interoperability", if the mapping is documented and reliable.

Sorry, I mean direct interoperability, as if the unmodified HTTP clients
were able to connect to http/0mq endpoints. For example imagine a SUB
endpoint listening on a http socket;
a http client like a browser or wget or whatever then connects and POSTs a
file which then can be interpreted by the SUB socket as a valid pubsub
message.

On the other hand, a simple HTTP transport encapsulation working as a tunnel
of the 0mq protocol, would not allow this scenario; both the client and the
server have talk the underlying 0mq protocol, with bidirectional
communication. I didn't dig in the 0mq protocol internals but I guess there
is some kind of handshake to handle the identities (perhaps it's optional?).

Cheers,
Marko
