[NLRS] Possible VHF rule changes & roving

[Jon Platt via NLRS]

Self spotting represents an added degree of complexity for a rover.  Yet more stuff to take.  2m APRS?   I have used it on a few occasions.  Does anyone have any experience with using their smart phone with an app going direct (ie, via cell, no 2m) ?  What app have they used and what kind of data usage to they see charged against their plan?
