I think they mentioned it was half the voltage of LiIon so maybe around 1.8v? Still pretty nice, but we'll see what the charging behavior is like before I get too excited.

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?

It's more like a geometric relationship. 100 people in a room, and each action is relayed to 99 other players. 1000 players, the load is 100x as much. If the server could only support 300 players, they would have needed 100x time dilation.

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.
