England. Well, it'd be just for fun.
I also had an idea of sending a locked-down ~£100 PC (complete with software for book scanning, purchases, etc and GRPS for synchronising to a main server) of some kind to a few major charity bookstores around the UK. Then I'd put up a website in a similar manner of Amazon, and people would rather easily be able to find very cheap books. Can't say that it's profitable (are you even allowed to put advertisements on sites for charity purposes?) but it sounds like a rather fun project.
