Hi Bruce, Haw,
I do not know if this helps for you, but there is an interface option
specifically made for anycast;
That acts like '0.0.0.0' (and ::0) but uses (weird) socket options.
This makes it pick up new interfaces when they are created (without need
for config edits and restart) or deleted. (This option is portable to
FreeBSD, Solaris, Linux, but probably won't work on other OSes).
