I'll preface my comments by saying that, as a libertarian, I'm a fan of pretty much anything that opens the US up to greater immigration. That being said, this reads to me more like a publicity stunt than an actual gateway to bringing successful entrepreneurs to the US. The effort required to hunt down qualifying talent overseas and to hook them up with VCs willing to make a (sizable) investment seems like it would make it significantly less attractive than finding a domestic startup in need of funds.

If they want a way to really bring skilled people into the US, they could start by heavily revising or completely doing away with the execrable immigration quota system: http://www.immigralaw.com/english/immigrationquotas.html
