Loadable plug-ins request

I'm fairly sure this isn't doable at the moment(though if I can be proven wrong again,
GREAT!) so this is more of a request than anything else.

It would be very nice if in a game like POG(or any other game that plug-ins are allowed)
if there could be an engine call to load plug-ins.

Starting and exiting POG 50-bajillion times to test a plug-in is a major headache,
especially on a slower machine. And maybe I'm missing something large and having a
feature like this would be extremelly un-doable, but it seems to me like there isn't
anything loaded at start-up that couldn't be loaded from the main menu.
