[MilCom] Airshows Remote Monitoring Video/Audio?

[Ken]

I'm surprised that someone hasn't commercially come up with a method that 
would allow hobbyist to subscribe (for each airshow) to be remotely "on 
scene" at various airshows, where there would be a live camera feeding video 
of the performers as well as offer a choice of monitoring various ground, 
atc, & aero performer frequencies at the same time.   Sort of like the 
NASCAR thing of riding in the race cars and seeing the action.

I know that some hobby monitors that are close to the airshows have had some 
limited audio capability.
