There have been multiple discussions on this over the past couple of years in the BackpackingLight Forum. They all end with this stuff being too brittle and too heavy to be useful in a backpacking situation, even though it does have incredible R values for a given thickness.
Addendum: Well, after reading the links from ikemouser it does look like maybe they are moving to a more useable material. The NanoGel product from Cabot is intriguing.
