Looking for ideas on controlling python module loading

[Nathan Coulson]

Hello, I am working on a client/server program (game) that uses C w/
an embedded python interpreter, that uses python to script what
objects do in the game. (primarily a C environment)

I was wondering if it is possible to control what modules get loaded
(or not). perhaps by determining if the hash of the local file
matches a hash provided by the server.

I was also wondering, if you could construct a module, without a .py
file, and define functions and variables.
