I feel like people are so concerned about infinite scaling that nobody ever tries to scale to 5 anymore.

I have a big collection of movies, and I’d like my mom-technical blue collar friends to be able to watch them. I trust them, and I have trusted communication channels with them. We exchange keys somehow.

With the sort of routing I’m describing, they could watch my movies and I wouldn’t have to have a public IP address. And I wouldn’t mind if their friends (that aren’t my friends) watch my movies, either, by forwarding through my friends. What’s the catch? This could work for that. How could I do this today?

I don’t have any ideological or moral problem with blockchains, I just think they suck at solving problems where the requirements for trust are low or met elsewhere.

edit: mom-technical was a typo of non-technical but I’m leaving it because it’s more accurate.

This is the part that doesn't scale. Hell, this is extremely risky even at a small scale. You don't know who your friends' friends are, you will have friends that abuse this, and you will end up with a much larger network than you anticipated.

How many of your friends and family are "friends" with bots on Facebook?

Definitely stealing mom-technical. Though I do disagree somewhat with the conflation with blue-collar. I would almost argue white-collar folks are less likely to understand computers.

I self host headscale as my control node of my tailscale vpn so no sign ins required, I just give keys out to anyone I want in my vpn.

My problem is the client doesn't support multiple servers, so I can't have a work vpn and a home vpn, not even with an easy toggle - you have to run tailscale with different conf options for both. Changing namespaces also isn't easy, so having friends and family segregated even on one server is also a pain point.

Thanks the main objection I have with tailscale is that you can't self-host (and you need external identity providers). I had no idea there was a self host option. I'll investigate. I assume it's an unsupported community option?

op is talking about headscale [0] "An open source, self-hosted implementation of the Tailscale control server"

I'd love to try headscale, but a bit of research shows that the tailscale macOS client requires a CLI param to connect to a custom server, registry keys for Windows, Android client requires custom compile, and there's no iOS client at all.

Unfortunately if I need to bring anyone into my mesh network who is non technical, this is now a non starter.

fwiw, those on the Enterprise plan can bring their own IdP :) https://tailscale.com/kb/1119/sso-saml-oidc/
