FCEU multiplayer mode?

view story

http://ubuntuforums.org – Hi, I love NES :) That's why I use GFCEU emulator. When I was searching in repository I found package "fceu-server". I've her already installed but I don't know how can I play with friends over the internet. Is there any documentation or guide to server set-up and little info about connecting? I saw also "Network" tab in GFCEU, how to connect? (Hardware)
