Indeed very interesting open-source application! I agree IRC integration would be really nice, it's one of my favourite features on Slack, allowing me to communicate with my team mates without changing context when i'm inside a server context.

I wrote a simple how-to to do it for Slack and would be delighted to contribute on this feature for Let's chat!
