My little company, Lone Star Press, has books and comics on the digital distribution site called WOWIO. In the past they have had some very public ups and downs, but now they're open for business with big plans. The Lone Star material does not have sponsorship yet so it's not free, but it is up for sale. At the moment, they are one of the better digital sites and they have my full support. Either way, it's an interesting window into the near future of indy comic book publishing.
