Does anyone know of reliable services for pay per view video? For one of our projects, we wanted to look at doing download for a fee style video instead of a DVD (with all the distribution issues of production, distribution, etc.) So at least we wanted to see if there was already something instead of writing our own code.

I guess I will answer my own question. It looks like Amazon Unbox might be the way to go. The site used to be Customflix, which is now createspace.com.
