Also, /dev/null isn't quite right. Consolefs only broadcasts what comes out of the console, i.e., the echo of the typed stuff plus output. You'ld need a /dev/echo. However, if you just hacked consolefs, you could do away with that and have a real IRC. > I was considering very seriously going that route for my own array of > low-power obsoletes, and my main client has a similar need with none > of the ready expertise I can throw at my equipment.

When we lose power someone has to run in and shut down the machines before the UPS's give up. Luckily, we only need that on our stand alone machines and the file servers. We also have a mixed environment. Pretty much everything imaginable is controlled by the plan 9 consolefs. The admins liked having secure access to the console server(s). We have 3 of them now, there are a lot of machines back there. We did have to wire DTR high on the consoles to some machines like the Sparcs, because if our console server rebooted and DTR went down and up (or is it up and down), the Suns also rebooted.
