Marq, you have worked on contextual search before. PTAL and see if still relevant.

If we decide to unify, it may be possible to move the implementation in to the Contextual Search component.  Most of the contextual Search code lives in the Android browser but we've been slowly working to move what can be shared into the component, and it should now have a layered architecture that's designed to be compatible with iOS.
