Is mirroring to the Apple TV reasonable on a campus network? Are there any better options like creating my own LAN? Or running a cat5 cable from my MBP to Apple TV?
Weather it will work on a campus network is dependent on their polices on wireless devices and network resources. I do know that AirPlay is going to need to find the Apple TV somehow and that would require networking of some kind that can dish out an address.
I would consult with the IT department of your campus. I don't think they would have a problem though unless they are really restrictive. Ball is mostly in their court though.
