Why don't you look at the Flexible Use of airspace system implemented in some European countries, with the use of TSA (Temporary Segregated Airspace) and AMC Danger Areas (TSA's just over international waters
)
The Airforce get to play all allone in a sector
within CAS, and the CIV traffic get routed around.
Here in Norway the ultimate goal is to have all high energy manouvering (ACM etc) training inside CAS within some years. Allready this type of training is
forbidden under some TSA's (class-G) due to commuter flights into uncontrolled airfields.
One such example is over the Lofoten Islands, where all flights in G under the relevant TSA have to bee performed in accordence with ICAO flight rules. This due to some very close calls between RoNoAF FJs and wait: RAF FJs in this area.
To bad the airprox reports is in norwegian only, they are scary reading.........
