if there isn't going to be any internal state, you could just leave out the
class definition there (and the self-references), and declare those functions
directly in message.py

then the test.py script could do something like

import ISC

ss = { "list": [ 1, 2, 3 ],
       "hash": { "hash1": 1, "hash2": 2 },
       "none": None,
       "string": "samplestring" }

s = ISC.CC.message.to_wire(ss)
ISC.Util.hexdump(s)

print ISC.CC.message.from_wire(s)

is that what you are looking for?
