The military junta who seized power in Honduras a few months ago is using the noise of pig grunts, amplified to be heard "at a distance of 20 blocks" to annoy the deposed President who is holed up in the Brazilian embassy. The army chief has said the sonic bombardments were a "serenade" to celebrate Army Forces Day.

How long before pig grunts are available as a ring tone?

How long before software is released so you can change someone else's ringtone? That, I think, is what would be called a Killer App.
