I want to see some (or a lot of?) chat history offline, and then send msgs while offline. I don't want it to scan the network, delay loads, or blow up in any way just because the network is down. Think about the Whatsapp or Telegram experience, as opposed to Slack or Facebook Messenger. If you are in and out of the subway, or in elevators, or just where there are spotty networks, the mobile experience blows for anything but the super popular and consumery chat services.

Unlike the people who can't figure out why this is better than IRC, I find a ton of value in your project. After leaving Campfire, moving to Kato, and then settling with Slack, I am really unhappy with the Slack mobile experience.
