Which is a nice though but to avoid any confusion: I'm just an ordinary user and not related to SJ in any way beyond that

This script might do the trick for you. It is very basic, it just calls the betacom.exe. If it works but more control is needed I could probably also have the script communicate directly to the sign.
Also it strips out single & double quotes to avoid commandline problems. No idea how betabright signs manages other special characters, but if the sign stumbles over some and you know what a regular expression is you can add some more characters to skip in the script ('skipchars' at the top).
Enjoy,
