You can not use keyword arguments with xml-rpc. Only positional arguments are 
allowed.

Also, Zope's mapply() doesn't like passing a variable number of arguments to 
PythonScript objects that try to use *args or **kw.

So, I've always just declared my exposed functions as taking one argument, a 
dictionary.

All xml-rpc clients just pass one dictionary, and that dict serves as keywords.

So your server function could be

params: d={}

and the client could call

Back on the server side, you'd use something like this:

first = d.get('first', None)
second = d.get('second', None)
