etkd--Good find! I think beneath the techie language is the Sprague patent that enables the user to activate an Internet filtering system that will search out for specific topics/items chosen by the user. And once found will be cached and encrypted on the user side, and decrypted if the user choses the content and pays for it.
See the earlier S. Sprague Information Distributing Patent, I posted to allman.
etkd, I think Wave will make the most money on their back office and attestation. Who's going to manage the money? An Englishman buys a French CD from a Belgian-run website that uses a German bank. Hmmm....
