I've been playing around with a CTF map and been considering the following sadistic setup -- basically a slide door with two bulletproof/rocketproofed windows on either side so that the engie can see through the door. Put a sentry behind the door, the trigger of the door is such that when the engie is in the tank position the door is open, otherwise it's closed. By manipulating the door the engie can protect the gun from sticky attacks.
The reason for this is the servers I've been on have players so good at demo man and soldier that no one wants to play engie anymore.
