Yes that's it.  We would like to be able to turn any object O into a
server (even if you do not have the source code, or it comes from an
extension in C, so you can not use 'normal' inheritance by changing
the object's Python class definition.  We do not want to change the
class X for all instances of X, but only the object O's class X.

That is what I am looking into now.  We want to define a 'port'
mentioning the operations that will be available.  Not all the
object's methods should be accessible via XML-RPC.  A list of strings
(method names) could be used, or an 'interface' sort of class.
