Well, It's certinaly mission creep, but so far the ruse has been to use part 121 (scheduled) airline service to try and limit access to the ramp, FBO and even private hangers and the smaller airports.
The folks over at AOPA are very worked up over this, even more so as the TSA are trying to do this under some sort of Secret Directive. Seriously, the TSA mission creep is getting very scary now, these guys are way outside their remit and no one seems to be able to stop them....
