What I do in my project is send google protocal buffer messages back and
forth. To figure out which is which, each time I send I wrap them in
another message that has two fields, a name and a blob where I serialize
whatever the real message is.

Using the built-in reflection of protocol buffers I can figure out what to
call each message, and using some templates and maps I am able to make use
of the protocol buffers builders on the receive side to build messages up
as objects. From there its just a matter of dispatching to various event
handlers.

It took a bit of work to get functional, but now that it works it's pretty
nice to just say send(whateverObject) and hook up some event handler for
that type on the other end.

It does feel rather heavy compared to what other people are suggesting
about enums and structs too :)
