I've looked at pyro, and it is definitely overkill for what I need.<br>
<br>
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.<br>
<br>
I don't find socket code particularly nasty, especially through a
higher-level module like asyncore/asynchat.<br>

So far this has been working fine, but I now need a way of separating
multiple chunks of pickled binary data in the stream being sent back and
forth.

Save yourself the trouble of implementing some sort of IPC mechanism
over sockets, and give Pyro a swing: <a class="moz-txt-link-freetext" href="http://pyro.sourceforge.net">http://pyro.sourceforge.net</a>
In Pyro almost all of the nastyness that is usually associated with socket
programming is shielded from you and you'll get much more as well
(a complete pythonic IPC library).
It may be a bit heavy for what you are trying to do but it may
be the right choice to avoid troubles later when your requirements
get more complex and/or you discover problems with your networking code.
