We also have that same PRS system here at NDSU where I am a student... I took an ME course that utilized the system and can say from experience that it was a useful tool.. it was IR and we never experienced any interference issues that I noticed - there were several receivers located variously around the room to help that. The system does seem to be catching on in a lot of courses.
