That's interesting. And I suppose a good solution to a current problem. But is somewhat ironic seeing as how it's by user cell/mobile phones that activists are being tracked/located, from the back-doors put in by the telephony companies (after lobbying from the USA who were doing the same but didn't want to lose a competitive edge). And I'm not sure how much good deleting the info will do unless it's forensically erased, and that can take time. Still, definitely a project to keep an eye on, thanks!
