Printing w/o distribution
Being the übernerd I am, I have to throw my $0.02 in.
I was looking over my newsletter from Cafepress. If you have a cafeshop, you will in the near future be able to use them to print and ship your publication. The specs aren't fully out as of yet, but they will be doing a softcover with color cover and b/w interior. You don't have to order a set amount, just it'll be printed and shipped if/when someone orders it.
They'll also soon be enabling data CDs and uploadable audio CDs (currently you have to send them an audio CD master for audio). This could be really good for a number of us, as if someone wants to buy a bunch of PDFs, they may prefer to have them on a CD, and again, there's no inventory to keep in stock. Other people may want a print book instead of a PDF, and they could order it.
I for one would be interested in getting a bunch of PDFs on a single CD.
