double simulation using Mission planner

#### Issue details
Hi everyone, I am not sure whether I am posting in the right section.
I was wondering if it would be possible to run a double simulation using mission planner.
here is my thought; I'd like to set a couple of waypoints on mission planner, have my quadcopter/plane following those waypoints on X-Plane 10 (using the SITL) and at the same time I would like to see the real quadcopter flying in the "real airspace"( following the same waypoints set on mission planner.

#### Logs
_Please provide a link to any relevant logs that show the issue_

The issue names Mission Planner, SITL, X-Plane 10, and Pixhawk but does not identify files, tests, or an entry point. First determine whether Mission Planner supports coordinating a simulated aircraft and a real aircraft from the same waypoints. Done would require a defined, safe workflow for both vehicles to follow the mission simultaneously.
