Newer versions of the ASIO C++ library support unix domain sockets on Windows, provided that Windows is sufficiently recent (Windows 10+).

Once our ASIO upgrade is complete (SPM-4010), we could add support for the server listening on unix domain sockets on Windows. Currently, unix domain sockets mentioned in "--bind_ip" on Windows are either ignored, disallowed, or fail here (I haven't tried it on Windows, so I don't know the exact existing behavior).

This Jira issue tracks both the Product the question of whether "server can listen on unix domain sockets on Windows" is a feature that we want for users, and the Engineering question of how to implement and test is reliably should we decide it's worthwhile.
