"Full" object and class pickling?

[Dave Brueck]

The marshal module can do code. This may help a little, it's not class defs
but functions:

>>> def foo(a,b,c):
... 	print a + b + c
...
>>> foo(10,11,12)
33
>>> import marshal
>>> q = marshal.dumps(foo.func_code)
>>> def bar():
... 	pass
...
>>> bar.func_code = marshal.loads(q)
>>> bar(10,11,12)
33

Also, FWIW, it may be easier to have the remote side request the .py file
for an unknown class (ie - you send it an object it doesn't recognize, so it
comes back and asks for that module). Then you locally use imp module to
locate and read the module's .py, zlib to compress it, and then send it out
over the socket. But this might not be an option in your case...
