Push notifications / C2DM for Kindle Fire?

Question

AFAIK, push notifications require a Google account to work (they piggyback on GTalk), so does that mean for apps for the Kindle Fire are doomed if they use the standard C2DM

Answer 1

You can't use C2DM to Kindle. I don't know why Dule's answer above says he could use Parse to push to Kindle - their service is C2DM and there is no mention of a Kindle client in their docs.

Urban Airship works only because they have their own client, which is fine, but it's not standard.
