Oh yeah. That'll get you.
Back in college, they cut access to the printers for users off-campus, which had previously been a feature. Someone I knew wrote a printing service script in AppleScript that, when fed a PostScript doc, would ssh into one of the on-campus terminals with the user's credentials and feed the doc to the printer. He got in a bunch of trouble because apparently, computer services had cut off-campus access for data-tracking purposes as prelude to an as-yet-unannounced shift to pay-per-page printing (i.e., they wanted to see how much inconvenience the student body would tolerate), and having the inconvenience routed around in software fucked up their numbers.
... now that I tell this story, it occurs to me that nobody ever called computer services on the whole "Running an unsanctioned social experiment on the faculty and student body" part of all this...
(p.s: I think, perhaps, computer services learned the wrong lesson here, because when they rolled out the program at a uni with a massive computer science program, the techniques the students invented to route around paying for print jobs were legendary. Things like "wrap the PostScript job in a detector that tells the daemon tracking pagecount 'I am printing one blank page' and tells the daemon that feeds the job to the printer 'here are the actual pages'". Perhaps their takeaway should have been "If you add friction and cost to the process, bored students will volunteer time to reduce the friction and cost").
We had a similar setup at my university - printing to a lab printer was disallowed from a machine that wasn't physically in the lab. The printers had routeable IPs, so I'm guessing they did some kind of whitelisting at the printer itself.
The problem was, we were a Sun campus, and my tablet PC ran Linux. So I could SSH in, open up StarOffice, and hit Print on a document - all from the tablet PC in the crook of my elbow - then walk into the lab and pick the documents up out of the tray.
I never got in "trouble" for this, per se, but I did have a lab technician once look at me as if to say, "that's not allowed..."
