I'm sure a digital book can be translated into any format such as Kindle or Nook, or as a pdf file, from a home computer. All that would be needed then is to set up a pay-pal account for interested readers to pay for the book(s) they want. That way the author sets the price and all proceeds are royalties.
As an option, I can see several writers/authors coming together and setting up their own publication company or distribution company using a similar pay-pal type account.
I have a son and daughter-in-law who are setting up an on-line referral agency for teachers and students to find each other and get together either on-line or in person. It's called My Dream Teacher (check it out at http:\\MyDreamTeacher.com), right now it's a free service). I'm thinking of having him set up something similar to market my novels and give him a percentage of the proceeds (assuming my novels ever sell, LOL).
