The campus is almost wireless right now- only the academic buildings need to be wired. All res halls, library spaces, and the COOP are wireless. You still need to log in every time for public spaces but for res halls, you just need to log in once. Probably something with cookies. It'll be entirely wireless by the time you come- including the town itself! So yuo can sit on the lawn on a pretty day....
No peer-to-peer networks.
The tunnel only goes through science buildings like Wynn to Olin to McGregory to Lathrop Halls. Nothing else. It'd be nice to have one that takes you from up the hill down the hill so no one falls on the ice in the winter.... like I did
