Thanks Simon and Dimitri, I wasn't familiar with the procedure for
attacking these sorts of things.

I've started a discussion on public-webapps, which will hopefully help
to clarify a sensible API. Please add your voice if you have the time
and inclination:

If the discussion proves fruitful, I will re-approach the WebKit
community to figure out the best way to work on a prototype
implementation. I've closed the previously mentioned bug for now.
