IMO, a standardized field information system would actually provide a lot more room for innovation. Right now, any team that wants to do something like your trackball-tracker has to develop it from scratch. That might be okay if you just want to look at one or two factors, like our tracking system this year, but I think that if you get up past a certain critical number(which is very easily attainable for an expert system), you end up spending all your time on the low-level sensor stuff, and not enough time on actually developing system that can use that data.
