Well, its a different binary that runs inprocess, so it will know what
kind it is at compile time.

I think we need to pick one, its just not that important which one.
Shm is obviously going to be involoved. Small write()s seem like the most
versatile thing.

You want the plugins to be as simple as possible (for performance reasons
if nothing else). I have to say i'm not 100% convinced that regex's are
the right thing, although I love them. We would need to specify the exact
regex implementation used as they vary a lot.
