Thanks for the comment, it makes us hurry up what we have got going. This was been proposed before and we actually have an alpha we're working on in-house. It actually serves two purposes: 1) when traveling and; 2) identifying those FTers close to home for other get-togethers.
As soon as we get a beta done, we'll release it for testing but again, we are only driven by the board and what you want your community to be. Great idea and thanks for any additional comments on how you see this working.
