seems like it only affects sound or wave functions in a specific frequency as determined by the speed of the air movement or electron migration rates or whatnot. Might not be very effective for general sound insulation unless it's fixed frequency, o (or else you'd hear the generated harmonics). Not too different than active noise cancellation.

This sounds like MO recording with sound waves instead of a laser. I don't see how this works with NAND flash though. Even if you can increase the number of voltage levels stored on a cell after heating, wouldn't each cell need to be exposed in order for it to be targeted by the ultrasonics?

If someone developed a botnet of proxying servers. As long as users voluntarily install tools that provide proxying services, the responsibility for its use falls on that user. However, if the proxying were the result of an infection by a recognized virus, then there's an argument that the user had no intention or idea that they were proxying material. Not that I'm advocating such an idea, but I believe that if proxied torrents become standard, someone will make such a virus.
