It would be fun to able to play with other users of optishot on-line. I'm thinking of buying my brothers their own optishot's for Christmas - we live in different towns, but it would be fun to duke it out with them when we can't make it to the course. We only get to play once a year given the distance, family, etc.
Thinking about it - this could morph over time into optishot leagues or tournaments - it could turn into a great online golf community! I could see it morphing very similar to what iracing.com is doing with it's racing simulators and tournaments. Checkout iracing on youtube to see what I mean.
