Cityside Cinema Club

Brenda has asked for ideas on how to fund the new data projector, and it fits in with a thought I had had.
Many Citysiders are into film. I've recently come across a thing called <a href="http://www.spiritualcinemacircle.com">Spiritual Cinema Circle</a> which is a subscription-based DVD club. It costs about the same as one of the rental DVD services here (when you do the currency conversion), but you get to keep the DVDs. Every month you get 4 films: A feature, a documentary, and two shorts.
The films are about spirituality of various kinds (not necessarily, but also not excluding, Christian spirituality).
My idea is that we get a group together and charge a monthly subscription, which would pay for a group sub to Spiritual Cinema Circle and also buy other DVDs, any remainder (or a certain proportion) each month to go towards the projector. Subscribers get to use the projector (and/or the TVs in the space) and play the DVDs; if you want to do so on a particular occasion and you're not a subscriber, you kick in a koha of a couple of dollars as a "temporary subscription".
Note that for legal purposes we're not charging people to see the films, but for the use of the equipment and access to the DVD library. Like the Cityside non-lending reference library of books, the deal would be that the DVDs don't go off site.
We'd need to work out something about booking regular and irregular times to watch the movies. I'm not sure how many unbooked times there are in a given week.
