In particular note:
Warning: The pickle module is not intended to be secure
against erroneous or maliciously constructed data. Never
unpickle data received from an untrusted or
unauthenticated source.
Pickle works great for lots of things, but combining
pickle and socket is scary. If an unfriendly can connect
to our socket, they can feed us a *poison* pickle. The
marshal module is at least as bad.
The marshaling in RPC facilities tends to be much safer.
