Unfortunately, it'd probably c) get fouled up really quickly because of sweat and d) block vent holes causing more sweat and an increase in problem c).

But that's something I'd be interested in trying (especially if it had a mp3 player mount up there too so no cords to snag or rustle against my shirt/jersey or pick up wind noise).
