Just a quick alternative suggestion.

Are you going to find yourself copying to multiple machines, i.e. are you going
to have "failback" system involving multiple clients?

You might consider taking a look at Spread, which is designed for the specific
purposes of interconnecting *multiple* nodes on a network, using a multiple
publisher/suibscriber model

http://www.python.org/other/spread/

I think the twisted people have a module called "spread", but it is to do with
distributed objects, not the spread toolkit, which is lower-level.

Perhaps a closer fit to your requirements? Just a thought.

HTH,
