It would be really cool if you could use something like this in-process to open a "socket" that just happens to route over wireguard or another VPN.

E.g. you could easily have a bittorrent client use a certain VPN without routing all your traffic over it, or you could have a tab container in firefox use one connection, and another container another connection.

In Linux you can also use network namespaces for this. Although you can't have your application run in multiple namespaces simultaneously, I think.

The websocket approach is a lot easier to configure, so I'm definitely going to look in to this.
