THe major difference between the markets (AUS and USA) is that in AUS sailing is a national passion. Where in the United States its barely known -- part of which I believe is the due to how US Sailing has conducted itself as an organization. Most people do not know that US Sailing is chartered by the US Congress as the national body of our sport and as such is responsible for its growth and management. Unfortunately, its history has been filled with petty issues and typical YC trivialities. (Am I slightly upset about US Sailing --yes. History shows that they have been hiderence in more cases that an advocate) I'm not saying that there are some really great people doing great work there but, they really don't have the laser focus that they should -- in my humble opinion.
As for technologies transfer into other events. Thats one of the things that I hope the series brings to the sport in general. Which should make it more "spectator friendly" especially when you combine it with tracking systems that show the spectator who is in what position on the race course (ie 1,2,3, etc -- all in realtime).
