What about educational/public internet access? (Score 1)

I haven't seen any comments about this (then again, I'm pretty oblivious to everything) but how would places like libraries and educational institutions that offer public internet access deal with this? Seems like any sort of penny-per-page scheme would totally defeat public internet access, either that or you'd be swiping a credit card before getting on the web.....which is just stupid. I doubt that colleges (as an example) could cope with paying the bills of everyone using their public terminals.....just a thought...
