For first tries, you could go and check SimpleXMLRPCServer - it's in the docs. Then there is twisted, and some others I believe. Running throgh an apache doesn't buy you much AFAIK - so just skip it for now for the additional complexity it involves. Callbacks aren't supported by any xml-based RPC I'm aware of - which doesn't mean you can't do it, but _how_ to do it is up to you: You need a way to pass a server the necessary callback information. It basically consists of the url to talk to. That by the way is no limitation of python, but of xmlrpc, soap and whatever. And last but not least I found that whenever I tried to make python SOAP implementations work with more than trivial WSDLs I (or the implementations...) failed - maybe you can tweak it into working by handtayloring the calls and proxies - but that is tedious, errorprone and certainly not the road somone want's to go. I personally always used apache axis in conjunction with jython to fulfill my SOAP needs in python. But then again, it's not python anymore - at least not when you need some cpython-only lib s. regarding the .NET stuff - don't expect much. Just because it uses a wire-protocol that is well known doesn't mean that the infrastructure build on top of it is easy to grasp - and it's not integrated in anything but itself. That's true for the JAVA-world either, btw. Sooo - concluding remarks could be: - soap and python - not so good - if you can, use some other RPC to interface .NET - like IPython, or win32, or even corba if you can.
