For clarity, this does work with the mac os version of Zed. I use it frequently to work on my GPU nodes. The one tradeoff that is a bit of a smell for me is that the preview version of the feature requires you talk to a centralized broker on Zed's servers rather than fully p2p between your local IDE and your own server.
This is supposedly temporary though IIRC (may even be changed already in a dev branch, not sure).
