Looks pretty sweet. What are you using for the message transport? Any persistance of messages? What's the typical end-to-end message delivery time? Is there a presence indicator?
XMPP. Yes to persistence, but not in v1. Yes to presence indicator.
This looks like a great library!
Just signed up for the beta. I'm assuming it will be sold for a fixed price once it's out of beta? Any plans for other platforms later on?
It will be iOS and Android for now, but we are adding Windows Phone/8 support if there is enough demand.
