You can use https://github.com/saljam/webwormhole if you want P2P file transfer.

It only has a CLI tool right now for desktops. It works in the browser though, so that is great for users looking for a GUI!

It is literally using the same wormhole-william backend that I am using for wormhole-gui. I don't quite see how that would be any different. Interestingly enough, I have actually never gotten that one to work :)
