I used to do tech support at my school (graduated in December)... We didn't allow students to have their own wireless setups in their rooms (even had a no-support policy for wired routers). Network Services guys would walk around with some sort of sniffer and find (mostly unsecured) WAPs then shut down the port. Not sure how thorough their testing was, but it was enough to catch several people each time they did sweeps. Students would call us and complain that their Internet is down, and we'd get to explain why. If they were caught twice, they were off for the rest of the year. They actually shut one down and four or five rooms called because they were all using that one WAP and didn't know it...
Best bet is to wait until she gets info from the housing dept and see what they say. Our pamphlets specifically said no wireless in the rooms.. Maybe put in a phone call to the residential networking folks and see what they say -- don't trust the RA or orientation leaders as we had some folks that said their RA said they could have their own routers and such.
That said, there was a guy that worked for us, and lived in the dorms, who had his on WAP in his room.. but he had it secured so that only he could use it and never had a problem.
