So at the end of the first season of Agents Of S.H.I.E.L.D., Fury has this amazing guest star, and by the end of it, his justification for reviving Coulson using T.A.H.I.T.I., a program that was meant to be used on mortally wounded Avengers, is that he used it for what it was made for, which is a really sweet moment between the two. It's also the passing of the torch moment where Coulson becomes Director.

Anyways, aside from the Avengers, who else would Fury have considered important enough to revive using T.A.H.I.T.I., obviously before it was blown up and burried under a mountain of rock. I think that he would have certainly used it to revive Maria Hill if she died, but other than that, I'm not really sure who he'd used it on aside from the Avengers.
Who else would Fury consider important enough to use T.A.H.I.T.I. on?
