Isn't the theory the same? Without the compressible gas behind the piston, the increasing volume in the oil of the advancing piston rod would cause both systems to hydraulic, wouldn't they? I think you're confusing application with theory here...
One thing's for sure; once someone does come up with a more tunable damper, that particular genie will be out of the box and may well turn into a source of regret for your class. Whenever things get more technically complex, and makes it more difficult for the average Joe or Jane to go racing, the class suffers. Off-Road is the ideal class right now, since you have that greatest of all levelers - more power than grip. As I said before, be careful what you wish for!

the main difference is that the nitrogen filled jobs of full size car shocks prevent cavitation as oils passes through the various valves and holes etc. as the Pookster said.
i suspect that if you tried the same thing on tenth scale shocks, the rods would get shoved frimley out to their fullest extent. i suspect also that forces aren't big enough on model cars to get cavitation.
other than that, i think the purpose is very similar.
But I aint no expert..
