Bert- Video is an awesome teaching tool and is super entertaining at the regatta dinners. However, in our case we have limited resources that aren't already sailing or doing RC, so it would be tough to do it right. That's why the virtual replay using smartphones (which everyone owns anyway) as data trackers seems so attractive.

Reason for the post is that I'm sure someone smarter than I has already thought this through and come up with the best solution. Just looking to sponge some knowledge from the collective brain trust.
