sounds highly operating-system dependant.

  some thoughts:

 put each module in a file, have the controller look four these files anf
 read what it needs to know from any correctly formatted file.
 in thois case given that the module uses no globals the file could just
 contain compiled code.... but then you don't ge to use library calls...

 But what gouild would such a module be?  - does it just do some
 arithmetic, or some data transformations, and return the result?

 to "activate" such a module just load it into ram and run it via a
 pointer.
