Thanks, all - sounds like either finding a cheap IRIG display or hacking up
a pi/arduino/etc. version will be the path forward.  The IRIG displays I
can find quickly on ebay are still priced for people building music
studios, so...

RPi 3 B+ supports PoE with an extra hat, and you can get pi-powered 3.5"
TFTs cheaply.  This may work best.

A friend also pointed me to some networked dot-matrix displays that will do
NTP from timemachinescorp, which might be a fun diversion. :); -Dave
