$600 is roughly 300 gigs in feeds transfer...
a customer who is enjoying the feeds on a somewhat regular basis might use say 2 gigs/month
that's 150 customers @ 2 gigs/month
if you're charging $30/month for your site, and 20/150 (13%) like the feeds enough to continue their membership, the feeds are paying for themselves. i think the number is quite a bit higher actually, especially if you're talking about guys who are STREAMING 2 gigs of content monthly through Sex Entertain feeds.
as long as 13% of your customers who watch the feeds are retaining, the economy is being stimulated and you're making more money
