Also, don't forget referee tracking. Higher level referees work hard on being the right places at the right time, so having some data showing their position at KMI as well as some way to measure their ability to anticipate would be valuable.

By now we're building a platform where you upload your videos and access your analysis, in contrast to others, we are not focusing on video recording.
