Make VoIP Calls While You Snowboard

I found this awhile back while i was browsing Gizmodo. Motorola has released a Bluetooth hat desinged for snowboarders. While I am sure this is intended for use with Bluetooth enabled cellular phones, I could see this adapted to work in conjunction with a Bluetooth enabled pda/smart phone that has a SIP softphone client installed. While I am not a snowboarder, I do ski and I am trying to get my hands on one of these to try out with my Cingular 8125 that has a Skype client installed. I will update later in the ski season!
