RPC Client/Server in one Module?

I have an RPC Client/Server which I would like to write as a single module. This way I could start the same module on multiple workstations with different parameters to RPC to any other workstation running this module.
Problem is, the way IDL builds the stubs, it means that when built as a single module the remote method call in the server stub actually calls the sending method in the client stub.
Is there any way, apart from manually editting the server stub file to call something else, to get this to work?
