The lobby system itself is not maintained by any one person, he spring lobby system has TASServer at the core, and there are currently 3 actively maintained lobby clients, 2 abandoned clients, and a flotilla of bots and autohosts.
As such you would not need to do anything yourselves once you've implemented the command line parameters, users would just use the same server as the spring people, and the lobby would handle everything.
Most of the battle protocols are ignored when starting glest games as they do not apply, thus implementing lest support in a dedicated lobby would be easy.
