The other thing about IR is that it bounces really well, plus it penetrates things you'd think would be opaque. In terms of rangefinding, as long as you are looking at something rather large (say, a wall) and had a good outlier-removing algorithim, then, sure. Otherwise, I'd say don't do it.
Aside from that, if we're talking about non-FIRST activities, I've heard that an ultrasonic rangefinding ring can be notoriously difficult to read (on account of so many transmissions coming and going at the same time), so, if you want to delve into some crazy algorithims in OOP, some programmers swear by artificial neural networks. Apparently, they are very adept at going through messy data and pulling reasonable answers from them.
