The Union of people’s thoughts on the matter is very amusing, though. People don’t want ads, or drm, or to pay. It should be totally free, effort be damned.
Personally my main criticism is that in schools certain editions of text are required. Ideally all problem sets and answers would be provided without having to buy a given text, and you can consult any resource that teachers the relevant material as a supplement, rather than an issued textbook.
Assuming the IA wins, though. It would be curious to setup a website where people can donate physical copies of a book and you download the ebook and can loan it out in accordance to the amount you have physically. Yes, this is a library, however unlike a regular library it’d be interesting to push this to the limit. Even per page checkout on demand.
