Ultrasonics are allowed, and the VEX ones are very high quality for the price and will interface to the RC very simply.
I think the odds of an ultrasonic collision are very low. I have never intentionally tried to cause one, but the sensors really aren't sampling most of the time. We never had any collision issues as far as I know all of 2006.
