My one recommendation for trying to develop/test any electronic scouting system is that as you develop/test the electronic version, make sure there is also a paper version you can fall back on. You don't want to suddenly hit a roadblock because all of the sudden at the event you can't connect your iPads to the aggregate system.

Set yourselves a hard deadline (a week before you leave for your first event is probably the latest you could make this), that if that scouting system is not complete (though you can always make iterations later) and thoroughly tested, you can fall back on your paper system.
