Anti-Cellphone?

While I have to admit nanotechnology tends to scare the bejesus out of me (and if you've ever heard of the grey goo theory, the possiblities of nanotechnology might scare you too); nanotechnology - like any technology - has the ability to use it's power for good. This specific example is the creation of paint that has the ability to block cellphone calls.
A New York company called NaturalNano is claiming that it's developed a paint that can block cellphone and WiFi signals - yet be toggled off to allow selective, chargeable access.
While it'll be nice to not be annoyed by annoying cell phone calls & hence they're even more obnoxious ringtones, one problem is that of WiFi networking. As the Hexus article explains, the blocking of WiFi would allow companies to charge for the specific networks they provide. This would be good for a business standpoint as extra revenue is a good thing, it might not be so good for the many of us who go to coffee shops and other places with WiFi access because we can't afford internet. Although, I'm guessing not many coffeeshops would use this technology anyway.
Also an interesting point is perhaps nano can be reversed engineered - hopefully mainly in outdoor paints - to allow places farther from cellphone signals to amplify the signals so they get for better signals.
Either way, I think I perfer the lack of cellphones in public places like movie theaters and it's inherent lack of WiFi access to the grey goo theory.
