Interesting. Of course, my twisted mind quickly came up with two questions:

1. How's it's resistance to gunfire?
2. How effectively does it contribute to shielding from radiation?

Oddly, the website FAQ doesn't deal with either one of these issues.

Good questions! I'd like to know the answers myself.
