I use my Ouya regularly, mostly for Bombsquad sessions, where there are 8 controllers plugged in. 4 of them are PS3 and the other are wired Logitech F310. Ouya is hardwired in via Ethernet into the router (or into a power-line adapter.... depends on what TV I'm playing) and even then, very rarely, people will tell me that they have problems controller their characters in Bombsquad. But, for the most part, it's pretty lag free. The biggest lag I've experienced has been with the regular controller, when I move too far away. Most of the time, the Ouya is on its side and most of us are sitting pretty close. Just took it with me this week on vacation and played a few sessions of 4 player ToTo Temple and Bombsquad, using 1 Ouya and 3 PS3 and didn't have any lag issues. But, we were right in front of the unit, so that could be why.
