ATV + VPN

I’m curious to know how I can get my ATV to operate across my university’s VPN. I’ve read one piece - http://discussions.apple.com/thread.jspa?messageID=5505718&#5505718 - that recommends an ssh tunnel to the host mac + a network beacon to a specific port.

It sounds like a viable solution, but currently beyond my realm of expertise. I would like to know if there are other solutions or even a tutorial for the preceding methodology within the forum.

Thanks.
