When I was in the Army, the 2-1/2 Ton and 5 Ton Diesel trucks had a rig for a spray can of ether and a cable to the cab. Not sure I'd recommend that remembering how many engines the shop I ran changed out. Of course, the GI's had little respect for the equipment they used, so that probably had something to do with the engine changeout quantities, too.
I wouldn't recommend ether except under very rare circumstances, given the chance of scattering engine parts.
