>How long would it take to develop and deploy a targetted version of a program? Not particularly relevant - they can require a targeted version of the program be developed before someone comes under suspicion. >What's the likelihood of the target updating their program during the useful window of time? Doesn't matter - they can require a force-push update system be built to silently update a specific customer's app version. The law is broadly enough worded that they can order whatever software is in their way to become broken upon receipt of a court order. >Is this timeframe going to be of use to law enforcement? Yes, because the law will allow them to force commercial companies to build automated, scaled systems. >If the timeframe is justified, what's the time limit? Is 'suspect' going to have their comms intercepted for the foreseeable future? At what point is the well deemed to be dry? We'll never know, because it's designed to be used in secret.
