If I were you, I'll keep watching this company real real close. I've talked about Orb Systems before. Here's an interview with their CEO.
Excerpt:
What’s your business model?
We achieve revenues in several ways. First, much like Yahoo, we have users who look through our interface to get to their content, so we have an opportunity for targeted promotions. If they buy a ticket or song or album, we’ll get a percentage of the purchase price. Over the next few months we’ll announce several alliances in the music streaming and video on demand areas, with a premium fee per month. We also private label our service. Sprint Broadband has a private label version of Orb, and we have a revenue relationship with them.
