I would be interested in what was unpleasant? I've run inets httpd servers (which I did feel maybe exposed too much functionality), and yaws servers and yaws seems just fine. maybe yaws_api is a bit funky, too. I don't know the status of ACME integration, which I guess could make things unpleasant; when I was using it for work, we used a commercial CA, and my current personal work with it doesn't involve TLS, so I don't need a cert.

Ports are not network transparent. You can't directly send to a port from a different node. You could probably work with a remote Port with the rpc server, or some other service you write to proxy ports. You can pass ports over dist, and you can call erlang:node(Port) to find the origin node if you don't know it already, but you'd definitely need to write some sort of proxy if you want to receive from the port.
