We need some investigation into the limitations of constantly running our app while the user is travelling:
Power consumption: Running a combination of sensors in the background and the cellular radio in concert with whatever the user is already running can drain the battery quickly. We need to know how aggressive our app can be such that the user can ride for...(TBD) 6 hours?
Other sensors: What sensors are essential, how much accuracy do we need, sample rates?
Data: Stored sensor data? Network usage?
Limitations: The iPhone and SDK can be 'restrictive' when it comes to background operations, is our app impacted?
