hey everybody, thanks for your input, i REALLY apreciate it!! So;
tchnclfl: Well i actually did just what you said lol i just had 2 little wires running out of my wall socket haha!! but here is a way to counter that although it would be messier and harder to accomplish:
install a whole arduino in the light switch ( would have to make everything very small ) and have a wireless receiver running with it. The power i would take right off of the light switch, so no need for dying batteries and such... some possible problems? Yes. But it does seem plausable, considering your able to make everything small enough, and you find a way to keep a constant source of power to the arduino some how ( the power doesn't stop when you turn the light off... )... i'd have to look more into it before i could tell you a definite better way of doing this, but thats one idea off the top of my head... also in a better situation, installed wiring would be present already.
John_ryan: although i did think of that using two sensor ideas to be able to tell if a person is entering or leaving, and (as stated in the video ) use multiple sensors to find where a person is located in the room to light the room up accordingly, i NEVER thought about what would happen if a second person was to walk into the room... i suppose you would need some sensor in the room to figure out if a person is there... so thank you for bringing that up!
and ArduinoAndy: Thank you very much for that informative info, i truly never knew any of that but i was very careful when installing it as not to make it anywhere near permanent. i just connected the relay using 2 wires i put in into the switch itself so that i could just snap 2 wires and the relay would pop out, in 30 seconds or less i could revert my main lights back. i also was very carefull not to cause any shorts, i rapped up the relay many many times with eletrical tape so no netal contacts that could interconnect or short could touch and cause a fire or so. i also don't use this system for long periods of time at all... some because of the fire hazard you posed and some because i just don't trust it fully yet, but short tests of no more then an hour or 2 seem fine to me... and i never leave my house or room with the arduino plugged into the usb so no relay control is taking place without me present, to keep it safe!
( and since its quick release, i could pull it out quick if a fire happened 
)
