In reference to northgeorgia post (http://www.satelliteguys.us/threads/312610-(GEOSAT)-microHD-Portable-power) about taking portable TV and receiver out to dish, I was doing that for a while but I got tired of dealing with plugs and cords.
I have two laptops with two different Skype accounts. One sits in front of TV, the other is with me at the dish while I make adjustments. Tuning must be done slowly as there is a tiny bit of lag between the two laptops but otherwise this setup works pretty well.
You could substitute any device with a camera for the TV laptop then network it to the laptop at the dish and it would still work.
