Lots of interesting issues here! I personally am attempting to set up an alternative to lulu.com that operates on speculatively transferred copyright for the purpose of helping homeless people in London with the 15% commission - as opposed to lulu.com's 20%.
Furthermore, it's about the new economic model of publishing, meaning the site is more concerned with selling copyrighted pieces and the submitting writers skills - rather then thousands of products that may or may not be plagiarized...
It's early days though, and I'm just one guy from London on his own in this venture, if you'd like to have a look and help out in anyway you can, either buy submitting something or just brainstorming with us, please visit!
