Even with compressed independent frames that never spend on future frames you get the transfer window lattency so you need a lot of unjammable bandwidth. Line of sight transmitters? Ir lasers? Kind of a hard problem though as you might possibly want to not light up the whole country with your communications.

And commodity hardware can't push frames without a lot of buffering. I guess they might afford custom display hardware but it's a complex problem too.

I guess it would be easier to just send the coordinates where you want everything dead and get the popcorns. Bonus extra is everything that actually is a threat but I doubt that it's a actually a big concern when doing CAS, although I guess a A10 pilot might be able to spot schoolyards and kids if they are not under pressure.
