@slightlyoff @mnot interested. Ties into packaging, perhaps. Needs further discussion / thinking.

Chrome will ship soon. I'm going to be working on shipping something in Gecko over the next three months. There is also interest from other vendors.

FWIW, Chromium 39 branch has Manifest implemented to some extent (missing CSP bits).

Discussed in NYC; happy enough to close.
