I've tried this tactic once and it actually worked on someone else who was playing Terran.

Build till you get to a Templar Archives. Research everything in the archives and build the following:

12 Archon
6 Dark Archon
2 High Templars
2 Dark Templars
12 Zealots
12 Dragoons

He actually had good defenses set up but this what I did:

I saw his bunkers and siege tank on the ridge but I didn't see the missile turrets right behind them so I moved a dark templar just till I could see it on the ridge and then I used a Dark Archon to mind control it. I watched as the tank started firing all over the place. A couple other siege tanks came foward but I took out the 2 bunkers with Archons and Mind control the other 2 siege tanks. I set the 2 siege tanks into siege mode and watched the satisfying results as I brought the rest of my archons/dark templars/zealots/dragoons and casued huge pain to them. Then I sent my High Templar to Psionic Storm the workers at the mineral patch and the ones rushing Vespene Gas to the Command Center. I took out all the workers but he was trying to build more! I sent all of my units and ripped the Command Center to pieces. I took out everything else and won.

I wouldn't reccomend this for Zerg because of those queens with spawn broodling, unless they don't make many queens. For Terran, I'm lucky that hadn't made Science Vessels yet. For Protoss, I doubt it with those Reavers/Obsever/Zealots/High Templars.

CreepColony's Opinion: Tanks may be able to take out your dark archons before you mind control them, so you might want to disruption web the tanks first.
