I don't know if you've looked at it, but my remote InputStream (see
http://logman.dev.java.net) was intended to make this easier.  In the smart
proxy travels an InetSocketAddress to get back to the server with, and a Uuid to
identify the user/context.  When the smart proxy deserializes, it creates a
socket connection to the server which it can then both write down and read from.
  It really makes it possible to do a lot more interesting things than just
using RPC calls.
