TL;DR this is a way to solve the "how to reference in-app package contents in a platform-agnostic fashion"
Relevant to us because it would solve a mammoth / ancient issue that's been around for us [1]. The full proposal is here [2]. FirefoxOS already uses this. Chrome apps use a version of this (a la chrome-extension://). Opera used essentially this proposal for their widgets using the widget:// URI. I suggest that we tackle this post-3.0? Thoughts?
