Consider funnelling further discussion here so I can unpack whether it's something that could/should be supported directly in this repo.

@anacrolix ,

I was suggested to integrate "wireguard"(wireguard-go) within exatorrent because it would be nice to have a single binary that can run torrent traffic through a VPN(wireguard).

Since the support must come from anacrolix/torrent library, what do you think of this?

[anacrolix]

Yes it could be done by implementing custom Dialers and Listeners I expect.
