Sending binary pickled data through TCP

[David Hirschfield]

I've looked at pyro, and it is definitely overkill for what I need.

If I was requiring some kind of persistent state for objects shared 
between processes, pyro would be awesome...but I just need to transfer 
chunks of complex python data back and forth. No method calls or keeping 
state in sync.

I don't find socket code particularly nasty, especially through a 
higher-level module like asyncore/asynchat.
