The cognitive load of the notifications is an interesting point that I hadn't considered; I can see myself being distracted by those in the workflow I proposed in my previous comment.
I wonder if much of this could be solved by OS-level functionality (or at least having it in a developer-accessible SDK) that allows the new "always-on" lock screens to immediately trigger an application on a single tap.
