Service worker F2F meeting - 26th Jan - San Francisco

Since many of those involved in service workers will be in town for the web
components meeting on the 25th (
https://github.com/w3c/WebPlatformWG/blob/gh-pages/meetings/25janWC.md)
we're having a service workers meeting on the 26th.

The meeting is being hosted by Mozilla
https://www.mozilla.org/en-US/contact/spaces/san-francisco/.

I've created an issue to discuss agenda items
https://github.com/slightlyoff/ServiceWorker/issues/806.

We have a couple of spaces left if you're interested in participating,
although we're going to spend the majority of the time on low-level details
and spec.

Cheers,
Jake.
