I think 2 Engi's could do a decent job of defending the intel room, and 3 Engi's and a pyro ould do a great job of making it an impenetrable fortress. With two more Engis's w/ Sentries on the front line by the tracks and all 5 teleporters from spawn to mid, you've got a very strong team.
I myself as a lone engi in the intel got 4 defends. I build on the ground level agains the wall, opposite the intel. That gives it enough range to hit any on going into the intel 'circle area'. A scout could pistol snipe but my careful hiding and repairing out lasted his pistol ammo. He ould run into the intel quickly and take a bit of damage, but I would run up and pump a shot into him.
That's my strat for single man base defense.
