It could go either way. Years ago Rosetta Stone pulled out of the library market, after getting a lot of brand name recognition thanks to library publicity. I think the assumption was that there users would pay for the software rather than lose access. They were probably right in the short term.
ETA:
Sure, but having a userbase of 500,000 doesn’t mean the price has to be 500,000 times the price for a single account. I think it is reasonable to assume that .02% of your patrons are going to be regular users.
