Unity Lobby
From Spring
UnityLobby is a lobby written by hollowsoul in Python. Getting it working right now is a little bit of a pain, but it is your only choice to play spring on linux if you do not wish to use wine.
Steps to install UnityLobby:
1) Install subversion. 2) Install UnityLobby dependencies. 3) Check out spring from the latest version, and Unity lobby from the trunk (https://taspring.clan-sy.com/svn/spring/). 4) Compile unitsync.so and copy it into UnityLobby. 5) Switch directories to the UnityLobby, and run ./Unity.py 6) Have fun!
