Doing research in a solid state physics lab, I can tell you that this article is worth nothing without the inclusion of the critical temperature Tc at which the "superconductor" starts working. Given that its some sort of ceramic, its a class II superconductor which means that it could possibly be one of the "high Tc" superconductors, a misleading title because they do still need to be cooled with LN2 (just not liquid helium, a much more expensive/difficult prospect). If their "superconductor" only works at .7 kelvin, it's not very impressive--there are lots of materials that do that. To quote (more or less) one of my lab mates "if I dunked my cat in liquid helium, it would probably begin to superconduct." In summary, the devil is in the details.

Heh, I watched the episode last night as well. But seriously, this guy is crazier than a green snake in a sugar cane field.

Follow me here: The average household is somewhere around 2400 square feet. Let's assume for simplicity sake that it's a box measuring 49'x49'x10'. That makes for about 6800 square feet of interior surface area. The skin depth for gold at 2.4 GHz is pretty close to 200nm, but to be sure that the vast majority of the signal is stopped lets assume a coating of 1um thickness. 6800 square feet multiplied by 1um yields a volume of about 6e-4 m^3 of gold. Multiplying this by the density of gold (~20gm/cm^3) yields about 12 kilograms of gold. The last time I checked, gold was something close to $1200 dollars an ounce, which works out to be about $508k. So all the guy really wants to do is use the settlement money to WiFi proof his house. And have a gold plated interior. And a little bit left over for hookers and blow.
