My “rhs” finally died. I updated the story page with some short notes about why and an interesting side note: “Radio” and MacOS X 10.3's fast user switching. Radio behaves fine in that environment, still picking up news, responding to local and remote web requests, downloading attachements, everything.
This doesn't mean that I don't have a backup plan. It's time to retrieve the G3/300 Beige box and make it the home server.
