you might be interested in these two references:

- Dave Winer describes how a remote procedure call (rpc) can be realised by
encoding the call (method, parameters, ...) in an XML message (document)
that is transferred via http. See

- The Open Hypermedia Systems Working Group (OHSWG) addresses a similar
problem as you described by specifying interfaces for different domains of
hypermedia and communicating them as XML documents (the documents are
transfered over TCP/IP using a similar mechanism as HTTP). For testing
purposes also a communication using Java's RMI has been realised. See
http://www.csdl.tamu.edu/ohs/ and
http://www.mmrg.ecs.soton.ac.uk/~sr/ohs/ohpindex.html for further details.
