Great!

You can see the approach I've taken in the QuickCheck test provider
source code: http://github.com/batterseapower/test-framework/tree/master/Test/Framework/Providers/QuickCheck.hs.
Basically, I just copy-pasted the relevant part of the QuickCheck
source code so I could customise it to my whim :-). I'm not familiar
with the QC2 API, but it's possible I would have had to do this anyway
in order to get progress reporting for QuickCheck tests without them
writing directly to the console (which is _bad_ when there are several
property running at once!) and to obtain the random seed.

Cheers,
