To turn Android devices into user-agents: Something that users can control as they please without requiring root-access. A big part of this, for an always-on, always-connected devices, is capturing network traffic and reporting it in a way that makes sense to the end-users who can then take a series of actions to limit their exposure but not necessarily eliminate it. Take DNS for example-- for most if not all connections, apps send out a DNS request first, and by tracking just those one can glean a lot of intelligence about what's happening with the phone and which app's responsible.
