No I am not.

I said I have interest, I also said you shouldn't repost after a single
bit of feedback -- there's nothing more annoying than trying to review a
large-ish and complicated series of patches when you get a new version
every other day.

But please do work on it, because I really don't have the bandwidth to
carry this atm.  By now there's been a fair amount of feedback, so a new
version might be appropriate.

I really do think you've got some very good things here. Please work on
it. I will try and review :-)
