Re: P2P, it's kind of making an impromptu comeback. If you want some trivia, IIRC, the developer of Conversations was on some trans-continental flight few months ago and realized that XMPP works just fine on the free onboard internet plan (being considered by the firewall as legitimate "social-usage"), except for HTTP upload. So now, when your HTTP upload fails, Conversations asks if you want to try again with P2P, so you can send your images for free from the plane :-)
