I wonder if you can't sponsor a conference or something (where sponsor=providing the service for free). I'm thinking along the lines of setting up a sub-chat with tags unique to the conference to allow attendees to discuss topics in real-time. This may net you some new users, plus would give you some good PR opportunities.
