As I see it, photo recon would be easy in a multi crew aircraft. Just make a crew station (like the bomb sight position) that lets you see through the camera viewport. For the single crew fighters these were fixed and the poor old pilot didn't get a chance to see what he would be taking a picture of, just get into the right position and hit the shutter release.
But that leads us to the problem of ground detail. For Photo recon to be useful we need enough ground and object detail to make the photo's useful.
Then it becomes a skilled task to interpret the photo's to make uses tactical decisions and attack plans. ie Hit the parked planes and it removes planes from the line up when a player respawns. Hit the fuel dumps and it reduces how much fuel is availiable. Hit the maintenance facilities and damaged planes can't be repaired for further missions.
It would be fantastic to be involved in a simulated environment like that.
I also think it would be cool to have a "fighter control" table where a non combatant player could plot the positions of their own side, and have the radar contacts of the enemy also displayed. They could act as controller (for want of a better word) that would co-ordinate their own sides aircraft and vector their fighters onto the enemy aircraft. I'm sure there would be enough players that would want to take on this role. From my experience it's the squadrons that are acting as teams that have most success, this would give them a way of co-ordinating there efforts. (of course getting enough of the rogue wolf lone fighters to follow the instructions would be quite a task

but that's what court martials are for!!!! ) If nothing else it might remove some of the problems of of 5+ aircraft shoulder shooting a lone e/a while a squadron of them are a few miles away shooting up the ground objectives!
