Very cool! I particularly love your attitude to piracy. Do you have any data suggesting that's resulting in positive effects for Pinegrow? It's good to do either way, but data there would be particularly interesting.
I've been meaning to do a review of Pinegrow for one website I write for - will definitely get on that now.
Incidentally, if you come up with a simple Wordpress theme solution, as you're suggesting, then you move Pinegrow from "Hmm, interesting" to "OH MY GOD TAKE MY MONEY" in my book :)
