I don't know for sure.

In the past, I was able to collaborate with a friend using an Emacs
extension called "Rudel", which lets two distant buffers communicate
with each other over the Gobby protocol.

https://www.emacswiki.org/emacs/Rudel indicates that the reference
implementation for the Gobby protocol is broken.  I have not tried.

So perhaps the required work is not on the Emacs side, but on that 
of the protocol and its implementation.
