The changes to the hacker public radio website are going great, in my opinion, as is the new scheduling system.

As self-appointed Minister of Opus Codec Advocacy, if you can't justify adding a fourth feed, I'd suggest polling the speex users (perhaps prepend a short recorded message to the .spx feed episodes for a while?) to find out if any of them can NOT handle .opus as well. (Opus' support is already more widespread than speex's is.) If there are no objections, I would suggest replacing the ~28kbps .spx feed with opus encoded at "--bitrate 20". This looks like it should be roughly a high enough bitrate that speech quality should be outstanding, while leaving enough bitrate for the possibility for the opus encoder to switch to MDCT mode ("CELT") when it detects non-speech sounds occasionally.

The quality should remain the same or probably even better, while reducing the file downloads by an average of around 25%-30% more beyond what speex already gets it down to.

Also too, sorry for missing the show recording. We're starting to hit our "busy season" here.
