Sometimes I use RealVNC on a Motion Computing R12 which has been used for various remote control things.
The weakest point of remote controlling will be the quality of the WiFi connection. Cheap WAPs will work, but not dependably or fast. Low bandwidth, or inability to compete with other RF may end up with missed cues.
The best I've used was the Ruckus Zoneflex 7700 series of outdoor WAPs. New ones are two or three thousand dollars, but work extremely well in the worst RF environments. Have used a 7762 Worldwide, even in football stadiums with over a hundred other active WAPs.
