Yes, I know Vatsim and other real-time global simulators (and I'm sure I will participate to it later on during my flight training) so I guess virtual Flight Dispatch is just waiting to happen. Students and enthusiasts would benefit a lto from it.
So you want to sell it to training schools? I guess someone will see its potential.
But do you really need approval/regulations from authorities? Do these simulators have such a thing? I'm ignorant about this, but I guess the only approval you need is from the users who will tell you if it's a useful tool or not.
