I can tell you it does work. I'm working in a lab painted with such stuff. No, we are not doing anything nefarious, but we had developments stints into wireless and radio technology, and having a properly shielded room to work in helps avoiding trouble with the neighbors. I don't think they would appreciate getting their wifi jammed when someone here is trying to find a bug in a sender or something like this...
Cool. Are you using anything beyond paint (mesh in the walls or something)? Also, what brand of paint?
It definitely seems like something that should be able to work (to some degree), but also something that it would be pretty easy to scam.
No idea what exactly was used. This was done when they built the building, way before my time in the company.
