using internet in libraries in small towns..

If anyone tried to upload gigs of data on the public wifi networks I manage, I'd gladly shut down their connection. Just because a institution is funded by public tax dollars doesn't mean they have an unlimited internet connection open for any and all to abuse. Internet for institutions is actually very expensive, most can't go out and buy cheap residential Internet service like a private citizen. The providers see it as a way to fleece the government. Libraries get federal e-rate discounts but there's strings attached, one of which is non-commercial use.
