My first thoughts were the DS’s pictochat or maybe PSP. No clue about how to use them like this, I doubt “modern” tools exist (yet). But it’s creative, interesting, and I like the needless extra steps…so I support it

These are the niche things I subscribe for. I need guides

Had no idea that existed, I wonder what the security is like

The biggest downside, as I understand it, is that it’s difficult to convince others to use your tailnet
