I am trying to establish an RPC connection to a device running VxWorks. It already has such a connection that talks to a Win32 MFC app; I'm told that the RPC stubs, headers, etc. were generated by rpcgen on the VxWorks side.

Python already has an XML-based RPC module, but of course that won't talk to the existing Sun-style RPC on the device.

Which is my better bet: trying to get Python to conform to the existing RPC or building (somehow) on the VxWorks device some XML-RPC code to talk to Python?

Or is there a third alternative, like using SWIG to get Python to talk to the existing RPC on the Win32 machine? Fourth alternatives welcome!
