I just had a talk (power-rushed a bit) yesterday at Pass The SALT 2026 talking about (my version of) latency hiding filesystems in userspace over the network. My benchmarks, setups, and how to make the magic wawaweewa work.

Basically it went the "sshfs over iroh" approach, and instead of OP's post, it has eager metadata file sharing, and on demand file access. It is still a work on progress, but you can use git juse fine over the fuse mount points without introducing a new tool (edit: but do note that I did not encounter problems with large worktrees, as I do not use them in my flow, and still has some quirks). And still have similar "cold path" access times.

I touch on some insights of hiding the latency, the direct Alice to Bob connection, and has some recorded demos. Goes the generic approach.

You can watch it here if you are interested, but its around 25 minutes.

The first part is about the Post Quantum Crypto, and making direct IPv6 connections work.

The second part is about the filesystems in userspace that hide the latency. (The second part is around minute 12:00, and I think it is the relevant part to this discussion/ thread).
