Detailed Description

I have a need for this, and I'm going to go ahead and start working on it.
I'll definitely make a PR unless you think it doesn't belong, but I think it's pretty quick and straightforward, minus any qualms about people attempting to use unix sockets on Windows, etc.

Obviously I'm interested if you have any input on how it should be done. It's just a rather immediate need, so I'm pressing on with it.

My current plan is to allow the listener to be set directly via SetListener and skip the auto listener init if it already exists.

Hello, could you explain why do you need this? What is your use case?

[trey-jones]

Sure - I just find it much simpler to manage UDS via naming conventions on a server that responds to many, many domain names. Rather than manage arbitrary port numbers I will just proxy each "site" to a corresponding UDS.
