ATV 2 and ATV 3

I have a jailbroken ATV2 in my study and also an ATV3 in the living room. When I want to see a non-iTunes movie in the living room I unplug the ATV2 en take it with me to that living room. A bit of a lousy solution.

Isn’t there a possibility to stream from the ATV2 to the ATV3 without (un-)plugging?
