First, allow me to congratulate you on the thoroughness of your
analysis, and the detail in your description.  I'm not sure we will come
up with the answer, but you have certainly given us good information.

How can it possibly work well?  You can bind a TCP server to INADDR_ANY
so it listens on all available interfaces, but when you connect as a
client, you have to provide a specific IP address.  You are not
providing a valid host address.

That's what I would expect.  For what it's worth, 10049 is
WSAEADDRNOTAVAIL.  I suspect it would work if you specified ::1 as the
address.
