Here is a sketch. http://rfc.zeromq.org/spec:4
Basically it's stripped down to the minimum, and should be parsable
with simple code. With regexps, trivial. Without, a little more work
but nothing as complex as XML or JSON.

Sure, but IMO that's more about semantics than encoding. I.e.
"subscribe to this string" as compared to "subscribe to this prefix".

Yes, a string or stream of strings. I have this horrid feeling we'll
end up back with XML but having written hundreds of thousands of line
of XML over the last years, I'd really like to find a simpler language
that covers our needs. Not just about less reliance on external
parsers but also less verbosity. Anyhow, ZPL is a sketch.
