It looks like the average revenue is $1/user/month. However, the "average" isn't very interesting because the typical person that signs up to this would likely be far above average--no one is going to pay $5/month if they watch a single video, but if you watch 2 hours/day that's a great deal. So it's hard to say what a "fair" price would be.
