Agreed -- I like this separation and like the fact that you left it out. 0MQ
is really just one piece of our puzzle. It would be nice if it fit in easily
with the other pieces we need.
And as I said, it is a great fit for the PUB/SUB bit, but here where most of
the code already exists it would be nice if there were some way to act as a
drop-in replacement for alternate transport types.

We're starting with C++ and Go, but will also probably want to support Python
components. So I don't want to use any language-specific serialization.
Protobufs are a good fit for us.

Very straightforward in the simple case:
// Setup snipped
if err = header.Marshal(h); err != nil {
return
}
head := header.Bytes()
// Send off to transport layer...
