D&D do have a practice frequency: 245.1
Not much good to the VHF only flyers, perhaps the GA community could lobby the powers that be to fund a VHF practice freq? Although, as Jim59 says, it'll be a tad expensive.
Other scenarios - "Simulating short of fuel, request steer to the nearest suitable airfield." As FantomZorbin said, the "simulated instrument failure, request a practice no compass/no gyro recovery to xairfield" should give the pilot and the controller some work.
Use your imagination - nothing too outlandish; like the practice speechless pilot who had a further practice emergency which was a bee in the cockpit!
