Well, this isn't the perfect solution, but you can create modules in
the system at runtime like so:

In your code:
>>> mymodule = generate_module() #As above
>>> import sys
>>> sys.modules['dummy'] = mymodule

Now, the user can just do the following:
>>> import dummy
>>> dummy.something()

It's not _quite_ what you want, since it doesn't automatically include
it, but it's pretty easy to do. Furthermore, if you standardize the
name of the module, you can just have the user import that by default,
and then use whatever dynamic content you've put inside.

Also, note that mymodule can actually be anything, although you should
still use a value that responds to __getattr__ (anything else would be
really confusing, and probably a Bad Thing).

I hope this helps.
