To reply to myself:

The factory model works, but is a step we *could* optimize away.

Instead of making a factory to make plugins, we could just have the single
entry point make plugins.  The factory is the COM way to do it, and the OO
way to do it, but I find it a bit awkward, though not terribly so.
