Another solution is to make Tremulous "syndicatable." That means loosely, make it so other people can and want to publish information about Tremulous.
For instance, what would someone want to share about themselves in Tremulous? Kills, win/loss record, favorite weapons, whatever. How do you prove you are good at Tremulous? Maybe an official tournament, bracketing, or skill ranking system could be implemented. What if tremulous could record and export movies to a common format (mpeg)? What if the tournaments/bracketing/ranking was "covered" by cameramen who publish the games on Youtube?
What is happening
right now in Tremulous? What map is my favorite server playing, and who is playing on it? Are my friends currently playing?
What vectors can this information be shared? Forum signatures (dynamic images). Social networking apps. Mobile applications. Instant messaging. HTML iframes. Flash apps.
If you spend the time to make something that works for you, your resulting marketing affect is multiplied by the number of people who care about the game.
