I have to praise the Miami-Dade Public Library system. Once I escalated my complaints about their new wireless service they have done almost (but not quite) everything I asked for.
They unblocked digicrime.com from the PC network. They are going to put into place procedures which allow on-the-spot blocking overrides for the laptops they lend out in the library (!). They regret that they don’t see a secure means of providing a similar on-the-spot override for users who bring their own laptops, as they think that would ‘compromise security’.
But most importantly, they’ve unblocked port 22 so I can use ssh! And they were very nice about it, too. (Please, nobody mention some of the things you can do with ssh tunnels, ok?)
