With my current patch you could just add a "special" string to sys.path, and
associate an importer object with it. However, this sounds like a job for iu's
metapath (which I also intend to implement, if only to show it's possible). Very
much simplified, this allows you to add inport hooks that *don't* correspond to
sys.path items.

I'm almost done with my note about this stuff; will explain in more detail
there.
