Not just other programmers. The OGL says open content must be easily distinguishable from non-open content. This has usually been interpreted to mean that that OGC cannot be coded in, but must be read in from a separate (text) file.
Your best bet is to go to the Open Gaming Foundation website and use the listserves link to join the OGF-L mailing list. Before asking there, be sure to check the archives. If the archives are down (they often are) mention that fact when asking, because the discussion has been done many times in the past on that list.

edit - to add that the d20 license specifically prohibits interactive games, which is why the first advice is to use the OGL alone.
