This seems like a very cool thing. Kudos to everyone involved!
A question, which perhaps misses the whole point: am I correct that Distrify doesn't have a website where one could find the films that are being distrified? It is entirely up to the filmmaker to have such a site for her/his own film, right?
But why not have a central Distrify site that does that as well, that lists all the distrified films? It seems like a fair bit of traffic might go to such a site and it could be an effective way to attract buyers. So if someone sees, for example, John Burgan's "Memory of Berlin" and buys it, they might then also say, "I wonder what other cool essay films this site has."
But like I said, I might be missing the whole point.
