Re: No hassle here.
At the universities I've worked for, the distinction between the "public" and "private" side of the network is pretty blurry. Mostly corporate network admins would be absolutely horrified. By long custom the networks are nearly wide open, with only very minimal packet filtering. (When you have dozens of independently-managed departments all wanting to do their own thing, locking down the border with a strict firewall is not likely to go over well.) Generally they use pretty extensive network monitoring systems to detect misbehavior, and null-route infected PCs until they're fixed. Dorm networks get particularly careful attention here.
