Nonrad: I don't see your problem. I spent a lot of time at Farnborough explaining to people that RA(T) is NOT prohibited airpsace and that one of the conditions of granting it is that other pilots should have access provided they make 2 way contact and obey ATC instructions. Even glider pilots operating from Lasham and Parham were happy with this. Treat it like Class D airspace and you won't go far wrong.
