You can *marhsal* code objects easily enough (hey, that's what marshal
was invented for!).

But that obviously doesn't solve all the problems:

Well, indeed.

This might be another motivation for not pickling functions; the
decisions get really hairy and basically impossible to guess
accurately, so Python punts.

pyro?

But there's a fair chance that your exact problem hasn't been solved
before and you'll have to work out your exact requirements.  Then you
can start looking to see if any existing frameworks can get you
off the ground quicker...
