I wouldn’t consider putting a camera anywhere on a goalie. On the chest is where most players seem to aim!! <img src="{SMILIES_PATH}/tongue.gif" alt="” title=”Tongue” /> And I’ve been hit soo many times in the head while goalie I’ve lost count.  I’ve seen them on NHL dvds tho; built into the front of the helmet. Oh and they had them in the Olympics in Turin for the refs.
They look pretty cool.
