A good IRC server, not client library - I want something where I can basically register channels and react to events in those channels. There's things like Twisted but it's very low level.
I've got a few applications I'd like to use it for, things like voip.ms's SMS. There are some extremely good IRC client and bot libraries, but nothing quite like I'd want on the server side.
I've been considering implementing it myself, but I keep bouncing back and forth about learning Rust first or just doing it in Python and calling it a day... Then I get big lofty ideas about a common IRC server being run by a daemon where other processes would connect to it via some IPC and have a nice client library where they could register channels and have control over just those channels.
