Although, it greatly depend on the venue, I think it makes most sense to run lights/sound from FOH. In high school, we had a tech table at the back of the house. Now that I'm in college, (we have a black box), there is a booth at the back of the house (at the top of the stadium seating) with enough space for the stage managers and the board ops. There is a space right next to the booth outside of it for the sound op, so he can hear. We just ran a really technically complex show from that booth, running lights, sound, and video all from the booth area.
