Well that makes three of us that had similar ideas and didn't managed to fully implement them before Christmas :-p
Mine's more early alpha stage (and on hiatus) as attempting Facebook integration was biting off a little more than I can chew...
I still think there's a lot of mileage in the concept though as I think there are some pretty key features (other than vendor independence...) that Amazon's wishlist and Best Buy's Giftag are missing. Happy to talk
