Hey Ed,
Have you considered adding feeds as a member bonus for your sites? I can give your users access to thousands of videos for as low as $25 a month. Even if your members do not use up much of the bandwidth, giving them access to this much content gives them the perception that your site is massive (which it now is) and helps create a better value to your member.
Feel free to e-mail me at
[email protected] and I'll set you up with a free two week trial.
