I haven't tested this, so I'm not positive it will work, but you could try launching a ship that uses a crew-containing module that is not a "pod" and see if is controllable without a link. If it's not, then you could edit the pod configs to remove all of the command parts, leaving just the crew capacity. (Alternatively, you could create your own folder and make copies of the command parts - just remember to change the names). Then you can use your alternative, non-command pods to get the effect you desire. That said, I agree that this doesn't seem like "cheating" to me. I always assumed that manned ships didn't have any delay because the control input was coming directly from the crew, and not from the space center.
