Sometime in early December, an idea hit me about an IRC client that would function sort of like Twitter's mobile client. It'd defer the task of maintaining the IRC connection off to a server and it'd expose an HTTP-based API for the mobile app to use.
Anyway, so that's what I've done. I wrote a web server / IRC client that logs chat data to a database. Specifically formatted data is exposed via HTTP so that it can be easily consumed by a mobile client. I used node.js and couchdb for these two components. I also have the basics of a iphone app. The app can be configured to point to any URL / port to use as an API.
These components are all open source because I think that's important. Since the server component is just an IRC client, it could be connected to BNCs like ZNC, and should continue to function just the same. Might need some BNC-specific commands, though.
I just wanted to show this and see if others thought it was a neat idea. The project is still hacky but I'm actively building it.
