I don't like the notion of such prompts being injected into the DOM. I
guess I need more Web 2.0&HTML5 cool-aid.

Can't we extend the existing window.status?
It's supported by some older UAs (and ignored by others, because of
confusing UI), but if the UI distinguishes page messages from browser
and system messages, it's usable (aside from a historical API, but if
browsers ignore setting the window.status to the empty string).
