A potential investor would exhibit great enthusiasm after a presentation but a few days later would back away from any check writing. When asked why, the investor would say that he or she had asked a brother-in-law who worked for NASA for advice and the brother-in-law had trashed the whole idea. The effect occurred despite the fact that the brother-in-law usually had little or no knowledge about the firm's technology or plans.
This was, in fact, a real problem during the Clinton years and I would not be surprised if it returned under Obama, the most anti capitalist President since FDR. But between Clinton and Obama NASA was unusually commercial friendly. I remember a piece in Space News by someone at Bigelow talking about how the difference was like night and day when a group of Bigelow folks went down to JSC to study the transhab concept of inflatable modules for their project. And COTS, unimaginable earlier, came to being during the Bush years.
That said, the unnamed NASA official was pretty much on the mark with what he said. Getting a new space craft off the ground is hard, as the folks at SpaceX and other companies hae discovered. There are still those, however, who equate "commercial" with "magic." The commercial development of space is vital, but it is not as easy as some people think.
