wireless nintendo 64 controler

I found the OneWire library but apparently we can't we can't define the speed of the signal so I don't think I can use it because the timing is very important :s

but the send4bit method have very interesting params

bit0 The 4 bits to send for a 0 (MSB first)
bit1 The 4 bits to send for a 1 (MSB first)

we can define the timing, the shape of the logic levels, so yes that sounds great but .....
I really don't like to plug the MISO and MISO pins together ... I found that a bit "dangerous" :s

Gordon have you some example of project where this practice is used ?
