I have no idea if these insurers can be trusted with $19/year, but it actually sounds like a pretty plausible business model. If you count up all the file-sharers on the net, and divide it by the all the fines and settlements ever paid to the RIAA, my guess is that it's way less than $19/year, which suggests that you could make a buck (or Kronor) at this.

Update: Travis sez, "This article estimates the odds of being sued by the RIAA at 1:1840. This works out to a break-even point of $34960 per lawsuit."
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
