Matthew - that technology actually exists - the company is called radargolf.com from memory. The plotting with GPS is also available on the TV broadcasts, and you can get handheld GPS devices to show you yardages etc.
However, beware the rules of golf (sarbanes oxley?) - the rfid chips wouldn't be allowed in competition as it is deemed to help you find the ball - personally think anything that speeds up the game is a good idea, but rules is rules!!!
