I found a couple of documents, including the following [1], which describe the setup with multiple smb.conf file, but it won't mention the multiple IP need.
it looked strange to me that multiple instances of smbd could bind to the same port... so I see why some other docs exposed the request you did.

It was the first idea we got, but I'd rather not pursue it if I can, because that would mean administer [security updates, and so on] three different servers.
