EGG, you can always self publish. What I mean is, book publishers and sellers are in to SELL books -- lots of them. Not a lot of them are interested in "experimental" books as you say: "unique story, unique format." There are some, I am sure, and it's your job to find them. The perfect match, a publisher who is looking for or interested in your project. But probably 90% of publishers out there are following some types of business model, and they want to ensure that their books will sell -- lots of them.
I think that's the thing that separates the writers and the publishers. The mindset. Writers sometimes don't understand why a publisher won't want their books. Every writer think they have something great and unique to say, and they should be able to express themselves freely (the artist in all writers). Publishers are mostly business people who are in the business of selling products. They are not emotionally attached to your work. There's a gap there. And as writers we need to know that gap.
The thing for us to do is to narrow and fill that gap. That means either a) write something that 90% of publishers would want (a techno-thriller? a hot romance?) or stay true to yourself and find a publisher who understands you. Then you have to think of markets. Who will buy your book? And how do you reach them?
