There might be a misunderstanding of what Tailscale offers here. There is no "VPN" in the classic "virtual network" way. With Tailscale, you can - as with Iroh, IIUC - connect arbitrary nodes to each other, where a node can be a device or an application (via tsnet). All nodes get CGNAT IPs and an addressable hostname, so there is one giant "network" of all your nodes with automatic DNS resolution baked in.

Doesn't tailscale require those all be administered and approved by one account?

> there is one giant "network" of all your nodes

From what I understand they're saying, the point is that you get easy connections to things that aren't "your" nodes, sort of like allowing me to connect one of my tailscale nodes ad-hoc to one of your tailscale nodes, when our accounts are not related in any way prior to us doing that, and without me having to allow your node onto my network or you allow one of mine onto your network and have to deal with the specialized ACLs for that, since it's just a direct connection between two nodes.

Yeah, I figured that in the mean time. It just didn’t occur to me because my use case is literally the opposite—having a secure company network where strict ACLs are the core value, not a nuisance. But if easy ad-hoc connections are your goal, Iroh sure looks like the better choice then.
