streaming data with XML-RPC

[Dave Disser]

I have an application for which I would like to use xmlrpclib.py.
However, I need to send large files over the network as well.  I
notice in RedHat's up2date program that the following is done for the
client side (error handling omitted):

s = getServer()
pkgStream = s.up2date.package(getSystemId(), pkg)
chunk = pkgStream.read(1024)
...more reading

What is needed on the server side for this to work?  Unless there's
some serious magic in xmlrpclib, just opening a file handle and
returning wouldn't work.
