The latest post from the very interesting exe.dev project (previously of 'I am building a cloud' [0]). They have a lot of interesting work that goes in to making SSH work with their system (eg previously [1]), and this is a continuation of that.

Using Unix sockets to transfer file handles is not a new idea, but using for SSH connections is interesting to me. I wish it were a little heavier on the details here, but otherwise this is an interesting approach to handling network traffic while maintaining zero-downtime upgrades
