Don't picture them as OTA firmware updates. Picture them as OTA navigation data updates (i.e. maps, charts, waypoints, airport info, etc...) - that's much easier to pull off.

The process right now is pulling out an SD card from your Garmin/Avidyne/BendixKing whatever every 28-days or so (that's how often the FAA updates the navigation database backing these avionics), popping it into your PC, using software/webistes that could be... much better designed (to put it lightly) and then going back again. It's not exactly the hardest thing in the world, but it's not exactly a walk in the park either (especially for less-technically inclined pilots, who just let it lapse, and click out of the big expiration warnings every time they start up their planes).
