Microbilling is an interesting idea, altho i think I would tend to call it limited billing.

I'm assuming you mean something like a billing system that charges a custumer, say, $5 to see a specific amount of material.

I think we have as an industry educated our customers to fear recurring billing and surprise billing. This is true not just for adult - its for all online biz.

One of the things I've wanted to see tried is what I think of as "fixed daily billing" - a customer pays $30 for 30 days, but they aren't limited to a month, they can spread their 30 days over say 3 months. When they log in, a "day" starts, but their next day doesnt start until after both 24 hours and their next login.

Now, I could be wrong, but I think we've started down a road in which people are way more suspicious, and credit is more expensive and less common.

And we have to figure out different ways to bill and exchange value for porn.
