Ah, that is the "moving target" problem I was talking about. In the old days,
the "inetd" spawned processes as per-service daemons once it got a trigger
(connection) to a port. It worked well in the 90s, including on my... Amiga 500.
That is essentially what the OP is looking for, and what a sad way to do it
with the directory structure.

Progress is not always... forward.
