if only getting external collaborators or non-technical users into IRC didn't involve sending them a 15-step howto on configuring screen and ssh and could be as simple as "check your email and click the link you get"

and, if only there was push button per channel access control set up out of the box so that some users can join some channels but not others! no, not channel keys, those are busted (what do we do when someone stops being involved in a channel? rotate the channel key?)

there's way more in slack than IRC, so there needs to be way more in a slack killer than IRC...
