I have a desktop application that communicates on localhost. I recently read that it’s advisable for the server to bind port 0 and then a free port will be chosen to avoid conflicts. I guess the port could be a configurable option. Although for my users it would just add confusion. I can see why the security conscious would not like a dynamic port though.
