No worries - I hope I got that right.
It's a super useful pattern, because if you allow users to supply the
import-strings, you don't have to care where the module is deployed.
It's up to the user to make sure it's accessible via the PYTHONPATH, or
what have you.
So - folks can update their code and add new behaviours without effort
on your part.

I think you're correct to be wary of calling Python's eval:

is there a python equivalent to eval?
I am setting up a few things that could allow the user to specify
a pre-build function but user A could specify a different
prebuild function than user B, and I need some way of handling this.
only thing I can think of right now is using
maya.mel.eval("python string")
which I really don't like the idea of doing that.
any other ideas?
