Nice idea. Feels like a version of the E-2, brought in line with the new realities of the cost of starting a web based business - http://en.wikipedia.org/wiki/E2_visa (government is always slow). Rather than requiring applicants to bring monetary capital into the country, they'd be required to bring start-up capital, as measured by those who will invest in it.
I actually am in the US on an E2 visa, and I founded and (still) run entp.com. In my mind, the investment requirement of the E2 merely is a way of your providing proof of your ability to achieve success.
