Hi Steven,

As far as I can tell you can do all this today (at least on Android) but you still need to deploy a native application.
A native application can start the browser with an URL holding the UID for example.
Writing a native application using WebView makes it even more "webbish".

Personally, I believe new standards should [primarily] address use cases which do not have [reasonable] alternative solutions.

A problem here is that the Web Security Model is ill-suited for a bunch of applications, (IMO) including yours.  That is, there are privacy and security issues which are poorly addressed by browsers that always must assume the worst.
