Jonas, your suggestions have a good point. I don't yet see a way around
having a sender id or push id though. I'll keep looking for a way to reduce
proprietary pieces in the API. But for the moment, the Push API as it is
seems hard to implement without proprietary extensions to it.

Thanks for your detailed reply.
