Goggle Cam
 

Just got word that Liquid Image will be releasing an exciting new product at CES on January 5 2010.
The Summit Series Snow Camera Goggle is designed for skiers/snowboarders but would be just the ticket for all you openfacers.
Just thought Id let you know to keep an eye out for it.
It was mentioned on this page:

Liquid Image Freestyle/Summit Camera Goggles (NOTCOT)

Could be hacked to fit to my visor I reckon!
