Pickled objects over the network

Right, I could use Pyro, but I don't need RPC, I just wanted an easy way to
send objects across the network. I'm sure both Pyro and Yami can do that and
I may end up using one of them. For the initial version pickle will work
because we have the networking issues figured out with it, just not the
security problem. So we may end up just sending strings back and forth that
will let us fill out an object's member variables on the other end. It's
much less cool, but it seems like it'd be more secure.
