I've seen people posit this question before, but never answered, but since wireless powermeter/HRM broadcasts unauthenticated readings over standard ANT+, couldn't someone pair their head unit to a competitor's sensors and really know when they're suffering? Could be a big advantage knowing if the guy who won't pull through on the break is really suffering, or if the one attacking on a climb is worth chasing. Obviously fiddling with your computer during a race would be suspicious, but what if you simply did it before a stage?
That's not even getting to the possibility for equipment sponsors to provide custom firmware that supports showing multiple sensors of the same type, rather than just a single source, simultaneously.
