Using flexnet actualy gives the sysop the option to decide where the 
remote packets need to go, this can even be a seperate frequentie if the 
local area is already saturated, the digis can anounce what frequentie 
that is in the same way they can anounce what the right path for that 
area is.
I´m not sure about you but when I´m driving I like to keep my eye on the 
road and not on the screen so pulling remote data is only usefull when 
you are stationary and as a result the data will be pulled a lot longer 
then 30 minutes or so.
I also understand that normal packet is death or dying in the usa so 
there sould be plenty of left over packet frequenties to use for this.
you can even mix the puch and pull methode if you are using a seperate 
frequentie for this system anyway, that can be done with subscription 
via a local igate for moving stations or remote digi for stationary 
stations.
once you enhance the system by using seperate frequenties for seperate 
purposes there is no stopping the inventions, afterall that path has 
already been set in motion with the alt input for trackers.
