FYI there are HUDs that are made for snowboarders and skiers that you might be able to adapt for sailing if you don't want to wait for glass!

Second this; while they don't have a camera or the Glass software, they are goggle mounted (choice of goggles) and have barometer, thermometer, plus are Android devices all on their own. Also, they don't cost as much, plus, you know, you can get them now.
