Yeah, I tried doing some of that kind of work and failed.

Well, unless we can convince people that this would really be a good feature (which, somehow, I doubt...), not really. Though if it can be enabled with a tiny patch to Python and then most of the magic worked in PYTHONSTARTUP, that might do... but I suspect it'd need to be fairly specifically coded.
