Thanks for posting this, Erich -- very timely and potentially immensely impactful to all of us. My first suggestion would be something already posted above: no campus WiFi in the theater. I have not run into this very scenario, but I recently helped convince a major hospitality firm here in Vegas to create a standard for new construction whereby all new venues (and existing venues, as they are upgraded) must have a dedicated A/V/L network that doesn't touch the corporate network and has a dedicated tunnel to the outside world (via a dedicated cable modem). Educating the corporate IT folks about the protocols show networks employ has also been very helpful: i find that once you mention multicast, port forwarding and IGMP (with snooping!), they quickly agree to a separate, dedicated network. Good luck, and please keep this thread updated as you sort through this -- I am curious how it all turns out.
