Does anyone have experience with the FHA Short Payoff Refinance program?

I've read a little about this program which is a federally funded program aimed at helping people who are upside-down in the mortgage on their primary residence. I received a mailing about this program, and as it would happen am upside-down on my mortgage. I can't help but be intrigued by the possibilities if this were possible. Anyone have any experience with this or know how realistic it is. Seems to be one of those too-good-to-be-true things, but nothing surprises me these days with how our government spends our money (i.e. $4,500 cash for clunkers, are you kidding me?)
