In what I am writing below, server is an XMLRPC server proxy with 
basic authentication transport.  

So, what is the right call?  Suppose I have a Python Script at 
the remote sitei with an argument signature:

	def foo( a, b, c ): ...

which I want to invoke via XMLRPC.  How do I pass the positional 
arguments?

If I have a DTML method foo, with keyword (that is cgi) 
parameters a, b, and c, I know I can invoke it remotely by 
writing in the invoking python script 
 
	pdict = {'a':1,'b':2,'c'3}
	getattr( server, 'foo')([pdict])

That is, by passing the the params dictionary.

Is the proper server call for a python script

	ptuple = (1, 2, 3,)
	getattr( server, 'foo')( [ptuple] )
