A worthy project and I wish them all the best with it.
I'm a bit of a lefty myself and think the Occupy movement is great. Even if it goes nowhere I respect them for making a stand. However, upon reading the synopsis of the comic, there's a large part of me that thinks that this could possible be a leeeeetle bit boring.
Obviously it all depends on the content, which hopefully will be amazing considering the contributors, and how the stories are told. Can't help think that some 'straight' stories could be dull. I've got time for political stuff like V for Vendetta or Maus, but I've no real interest in any straight-laced tree hugging true-life tales of protestor power. It turns me off.
This could just be my preference for comics as fiction and escapism.
