Indeed. Fortunately the router's not connected to any other network, and
we own it.

Bonjour sounds lovely, but one of the requirements of the system we're
building is that it exists. :)
I'm not sure if Monte's Bonjour external is available in the Community
Edition (is there a page somewhere that lists which features of which
externals are available in which LC editions?).
But even if it is, it covers only Apple-branded OSes, and we need
something that covers all the platforms LiveCode supports.
I may get back to exploring why UDP broadcasting didn't seem to work for
me, but for now at least I have a means of automated discovery on our
modest local network that lets us explore the other parts to see if
LiveCode will be a good fit for what we need to do (the Raspberry Pi
requirement may be a deal-breaker anyway, but we're considering other
tools as a Plan B if we can't resolve the RPi crasher in LC).
