It's got a way to go to be a full replacement but it's already got a lot of the features and can handle huge amounts of images and videos.
It's fully open source and not for profit, if you also don't like our Google overlords having all your data, give it a try!
One side note: It looks like the generated pages don't process newlines from facebook properly, so stuff like bullet points just end up a jumbled mess which doesn't look ideal. Also it might make sense to include a link to the facebook page in the left hand bar under address and email rather than hidden away in the logo at the bottom.
I'll keep an eye on this site and this thread, I hope you decide to drop the pricing as I think it's a great idea and you'll get a lot of customers with a lower price point!
