Seems like it would be (relatively) cheap advertising to just have the server running work orders in the background. You could even do silly things like offer a small discount in the gamers front for team members who contribute X work hours for the team. That would basically be subsidizing your customers to increase the team's rank (and thus, exposure). They even provide widgets to display on your website. Just a thought.
