I've heard of these services (basically a basic shell account for irc) and I'm curious in running one for some friends as a trial run for doing it on a bigger scale.
What kind of software would this require? The implication is that the user would only be able to run screen/tmux + irssi/weechat and a basic text editor for working with their config files. They would not be able to list or change directory to anything outside of ~/ for that account.
I may be way off on what I'm looking for. Any advice is appreciated.
