The PushClient currently has functionality for checking permission and
registering for push. Exactly which parts of this are going to be duplicated for
Frame vs. Workers?

[Michael van Ouwerkerk, 2014/11/12 12:05:25]

There will be no duplication. Requesting permission will hit this client, and
hop to the browser process to do that. Fetching the sender id from the manifest
will also hit this client, but will stay in the renderer to do that.

After that: register, unregister, getRegistration, and hasPermission will flow
through platform. The register call will use the sender id as input. It will be
rejected in the browser process if it turns out no permission was granted. This
way, all these calls can be run from both document and worker contexts.

You already have a Push API block around line 333.

[Michael van Ouwerkerk, 2014/11/12 12:05:25]

Done.
