Spray-on Antenna: Fact or Fiction?

I fantasized of using spray-on antenna for DAS world, by starting a business of those motivational posters you see hung in the offices (see one sample below); but in reality, it would be an indoor antenna. If nothing else, I can probably spray it on my balding head and become a human antenna.

But my excitement has slowly fizzled. It's been almost a year, and haven't really seen any spray-on antenna. Back in February of 2012, Chamtech stirred up RF community (at least me) with a claim of developing spray-on antenna, it said was more lightweight and energy-efficient than current technology. The antenna can be "painted" onto almost anything, including trees, walls and fabrics. Anthony Sutera, CEO of Chamtech, even presented this at Google's inaugural "Solve for X" shindig.

I tend to agree with the article that this may be a hoax. But then again, it can be a genuine invention, and government just decided to put it into Warehouse 13 - just like they tucked away the invention of Cold Fusion (Fleischmann–Pons claims of nuclear fusion at room temperature).
