I dragged out an old utility I wrote last year and fixed up some of the bugs. nwall is a version of wall that uses GNU readline and sends text one line at a time. It's sort of like IRC for the local system. It's quite handy, and it logs everying to /var/log/nwall.log so you can catch up.
Elise has been bugging me to update my advogato diary, and I told her to write an entry and I'd put it in here. She hasn't done so, so I think I can avoid her nagging me to do my kernel class homework for a while.
