It's the Flash side that's slow, not the Python one :)  Python merrily 
spits out an array of 1000 small items into XML-RPC in way under a 
second.  Unmarshalling it on the other end in Flash took noticeably 
longer.  I've taken to stripping the Flash XML-RPC library down to its 
minimum, but it's still rather slow.  The Python lib is more complete, and 
written in Python, but it's still quite a bit faster than Flash.
