I think that if everyone clicks the warp key then you should all begin to warp at the fastest warp allowed. For instance, if you all click it but someone is near the atmosphere, the speed of the warp will be based off the person near atmosphere. That way, you don't all have to go to the command center and such to warp, but it also prevents the person near the atmosphere from being blown up. (I actually do not know what would happen if you forced warp someone near the atmosphere, but I am sure it is not pretty ).
