Your comment "Our internet connection is no longer the fastest service around" really hits home. Our users complain that they cannot wait to get back to their parents' house or to an off-campus friend's house so they can finally have fast internet service again. Even though ResNet is much faster than 56K dialup, there is no way we can compete with 1.5 - 2 Mb cable modem services that are now widely available. We would have to have an OC-12 just for ResNet to compete.
As for alternative services for University-owned housing occupants, at UCSB it is not allowed. We run the phone service and the cable television service on campus and for our off-campus apartments. We do not permit residents to install alternative high-speed internet services of any kind, and the providers are perfectly aware of this.
We are not, however, concerned as much about security as just network design and management. As you say, if a multihomed computer comes up on ResNet as a rogue DHCP server (using Windows ICS, for example), you then might have a bunch of ResNet students sharing someone's cable modem connection. Not a good thing...

Subject: multihomed resnet users
Is anyone having issues with rooms connected to Resnet via ethernet and an outside internet connection like a cable modem or DSL?
Our internet connection is no longer the fastest service around. Evergreen housing residents who want faster internet connections are signing up for cable modems, which seems reasonable to me as it makes them happy and gets traffic off Resnet. However some people in our campus IT department are very nervous about the possibility of a multihomed machine in Resnet circumventing the campus firewall. Resnet is a network segment inside our campus firewall so students can access file shares on student use servers in our labs, but the segment can't access our administrative db servers. I don't want to move Resnet outside the firewall as that would cut off access to machines in the labs.
I've updated our RUP to prohibit multihomed devices, but that doesn't make our administrative IT folks feel much better. I'm not even sure how to detect a multihomed machine on our network, the only one we've found so far was easy to track down as it was also a rogue dhcp server. Any advice is greatly appreciated.
Thanks,
