I very much like JAX-RS API, which works on both client and server. And certainly wouldn't
want to reimplement all this from scratch. I think this should be compatible with protobuf
(and maybe with Hessian), as well as JSON or anything else.

Cayenne doesn't, but Cayenne needs to have access to an object that does. ClientConnection
is this object now.

We can. It is not incompatible with JAX-RS idea. JAX-RS layer though will need to know about
HTTP details.
