OK, I'd call that an unqualified success. Put down a test track using a laptop (Argo) as an X terminal, talking to the recording machine (Harmony) running as a pure server. (Harmony actually had an X login screen showing, but nothing was happening on it so X wasn't stealing cycles.) Clean as a whistle, even though the laptop with its mildly annoying fan was just a foot or so below the guitar mic.
My other home computing accomplishment over the weekend was that I finally figured out what was wrong with my mail server -- people who reply to, e.g., steve at nova.thestarport.org should now get through. The winning trick seems to be adding *.thestarport.org to the relay_domains config variable on the gateway's copy of exim4. Possibly in combination with a wildcard MX record on the internal DNS server -- it's there, I just don't know whether it's necessary. Maybe a mail expert could chime in with an opinion. Unfortunately Debian's favorite mail server doesn't seem to be particularly well-documented.
