To get spots to all show up on the same tracker page they need to be registered to the same account. To get them to all update at the same time we spoke about starting the tracking at the same time - at the skippers meeting for example. People could then go fasten them to the boat or crew.
There are apps out there that can make all the spots show up on the same map. Offroad enthusiasts are all about the spots for their expeditions and the ability to call for help.
I can see it's possible to get spots from different accounts to show up on a 3rd party app - it's just integrating data. To be honest I did not think the spot tracker page is very well executed and a 3rd party app could be a lot slicker. (anyone got a link to an example?)
The synchronization issue is a little trickier. Has anyone validated the theory that if everyone starts their spot at the same time then the updates all occur at the same time? Without synchronized updates the spots are pretty useless for tracking race positions - but remain useful for figuring out where the stragglers are.
