Just a bump that this is still around,
The ifMUD is much more robust than IRC. IRC, for example, doesn’t let you recap channels if someone chatted while you were offline.
You can do that with IRC, but you have to set up a bot to do the recap.
In lambdamoo (my own installation of) I did the opposite thing: IRC ‘city’ with ‘houses’ (each house - one IRC network) and ‘rooms’ (channels) that connected to IRC from inside MOO.
One particular channel on local IRC was held by a bot programmed inside the MOO, and it could even execute MOO commands given from IRC. That wasn’t hugely popular, as I remember now.
server is racist; IP can not be used to connect to the Mibbit network id#v0418
