> what is the impact of this development work from the security standpoint of (potentially stealth) voice/data interception I think those things already exist, the Stingray is just the most-publicized of its ilk. Big price tags provide plenty of incentive for closed-source implementations, or possibly just licensing something already made. The open-source versions often serve to democratize or to remind, of the possibilities that've existed for some time. I think it'll enable some small-fish to do bad things that the big-fish have been doing for years.
