@aks the closest one can reliably get to that idea right now is an #Ergo#IRC network with first party gateways allowing access from #XMPP and #Matrix. I run such a network and while I wish the current gateways had better #IRCv3 support, it is working quite well overall.
Holy Crap it's Twitch chat working in @pidgin 3.0's brand new IRCv3 protocol plugin!! We have a long way to go, but this is all new APIs working and doing their thing!! #OpenSource#Twitch#IRC#IRCv3#ScreenShot
