I was actually planning on using XML-RPC for transfer of 'naked' data only, not HTML.
One thing that intrigues me is that Python and JavaScript are actually quite close in their syntax of data types: [] for lists and arrays and {} for dicts and 'objects', respectively. Replace 'None' by 'null' , lowercase True and False and you are there. Parsing the received data then is just a matter of calling 'eval'. 30 lines of code on either side, and you are able to exchange arbitrarily nested data.

I know there is XMLRPCServlet. Has anyone been using that with a JavaScript client? If so, what was your experience?
I haven't used the Javascript XMLHttpRequest myself, though I keep planning to try it. I don't get the impression it is usually used as XML-RPC, though I'm sure it could be. Often the result returned by the server is itself HTML (e.g., an HTML fragment that should be inserted into the page somewhere), which isn't valid XML-RPC. Unless you entity-encoded it or something.
Anyway, XMLRPCServlet is a fairly thin wrapper -- if you read the source it should be easy to understand. You could use some of the same mechanism in your servlet without involving xmlrpclib.
