This is one of the core things I've been working towards with DNTLS [1]. I love the idea of tunnels, especially for sharing between private parties. The SaaS providers (Tailscale, Cloudflare, etc.) have done a good job making it really easy on their infra, but it really blurs the line of "self-hosted" to me. Ideally we end up with solutions like this that can be run entirely without an intermediary.
If that's all that was necessary then I feel like a lot of these SaaS tools wouldn't be as popular. I suspect a lot of Tailscale's success is because wireguard is not easy nor does it solve the full problem space (i.e. discovery). With `tailscale serve` I can get a private HTTPS endpoint to my local machine in almost no time.
No port forwarding. No public IP required. No special proxy to set up.
Iroh already runs public relays. Your two computers will signal through those, and then port-knock and form a direct connection to each other, perfectly encrypted.
We just need to define a new https:// url, like ... let's call it "irohttps://" maybe, so then you could contact my laptop with "irohttps://<hash>/path?query".
I forward port 80/443 on my router to port 80/443 on my home LAN nginx webserver and point my domain name to my home IPv4. Then I put files in directories. It works great and has worked great for a couple decades. While the number of static nginx vulnerabilities that have come out since AI became good at coding has increased I still haven't run into one that applies to my simple static nginx setup. All this tunneling and secrecy and credentials is... well, it applies to some cases and I don't want to dismiss those. But it really doesn't apply to most human person's use cases. Just host a normal server on your home IPv4. There's nothing to break.
I don't have the code at hand, but I think it's better to just have a nginx server that only serves content if the browser has a specific certificate installed.
That way you generate a key pair, share the public key with anyone that you want to share the content with and that's it.
Downside is that some browsers don't handle the certificates properly (especially on phones)
While I do appreciate very much the "we already have the technology, let's just use it!" approach + the self hosting aspect, one of the downsides of self hosting without a proxy is having to expose your endpoint and likely having minimal defensive tools.

so... ICE/TURN/STUN ? Sorry I forgot which one of them actually works, but they do work
