A simple chat network based on RSS 2.0 feeds and websockets.
Each user has an OPML file that lists RSS feeds of people who are part of their network of friends who they want to communicate with.
It defines a chat space, which is public -- but only the members can post to the channel.
It's designed to work well with FeedLand.
If you use FeedLand, then the OPML file can be automatically accessed through FeedLand. You can add or remove feeds by subscribing to them or unsubscribing.
When you post something to the app, it's automatically added to a feed it maintains.
