I got a phototransistor and an IR LED and can send the signal but only a few inchs :p I need to figure out a circuit that could provide more range, im fairly sure the LED sending the signal is fine but the reciever needs to be more sensitive, perhaps a converging lens would do it, i'll give it a try.
I'd be careful, though, as your comments about that made me realize IR may not be the best way to go. I fear, if we use IR on more than one controller at a time, we may end up with too much interference, and the two controllers would end up cancelling each other out. It's kind of like having two remote controls for the same television. If you point either one at the TV, it will change the channel. We would have to figure out a way to adjust the frequency of the IR (I haven't played with IR in a very long time, so I don't even remember if you can easily get adjustable IR transceivers, or if you have to get two separate ones set to different frequencies).

Also this method has loads of interference, i don't know much about IR so dont know anything about sending signals with it so im probably doing loads wrong, but at least im getting somewhere.
That's kind of what I commented on above.
