Twisted (http://www.twistedmatrix.com) has an asychronous remote object 
protocol, with support for references, copied state, security, and lots 
more. The protocol (Perspective Broker) also has implementations in Java and 
in Emacs Lisp, and could be implemented in other languages as well.

There's an introductory document at 
http://www.twistedmatrix.com/documents/howto/pb

For simpler cases, where request/response is all you need, XML-RPC is a 
great choice, since there are implementations in most programming languages 
in use today.
