Adrian,

This is, in a sense, how web accessibility implementations work today. Each
OS vendors created an accessibility API (AAPI) that passes a specifided set
of information through the browser to the assistive technologies (AT) that
needs to interpret and interact with browser content.

Using this paradigm the wallet would be like the AT.

I think it is a superb spproach/idea whether or not Web Notifications turns
out to be the vehicle that can acheive this or not. It sounds plausible
though.
