I was thinking recently about the value of cyberears as a tool to covertly gather information on conversations being held nearby. Then, a thought occurred to me.
I have experienced, first hand, the powerful masking abilities of white noise generators. What if they could be purchased from in game locations? Perhaps they would be for corporate only use or perhaps they'd be around the price of some of the more expensive SHI products, but I think they could present some interesting challenges to trying to spy on someone.
