Send data to another server


is there a way to send data directly to another Unreal-Server (dedicated or not)? I know that it breaks the server-/client architecture a bit, so I fear that I have to rewrite parts of the server itself.
I know that you can send data to an external server via SocketIO or Varest and you of course can retrieve it from there as well, but that is not really a good solution.
The easiest way would probably be an SocketIO server in UE4, but it seems like the plugin only includes the client. Same for Varest.
Both servers will be in the same local network, if that helps.

Bump! Anyone? I am curious about this as well.
