I think this is a good idea. The whole idea of people syncing their own data doesn't work though, it gives too much room for people to fudge their data into the system so it favours them more. I think the idea is good though. I think there would be a fight though to say who is the aggregator of the information. This would also mean whoever does distribute it has a stranglehold on the industry in terms of how and when it supplies this information. I can see it's uses but I can equally see a lot of cons for the system not working or some serious amount of anti trust. If you could get an unbiased 3rd party involved though and they built the database then I think that would work.
