I mean something to tell the kindle how to read the file despite the drm. I don't know exactly how the kindle DRM works I haven't researched it but there are limited ways to do these things at least limited offline ways. To keep the file from being read on unauthorized devices you'll need to encrypt it somehow. To decrypt it you'll need a key. The kindle could have keys in firmware like a dvd player but that would mean the same key could open any file so any kindle could read any drm kindle book.... not effective. The could send the drm'd file tot he kindle wirelessly and send the key wirelessly and hide the key somewhere in the filesystem where people won't be able to see it. They could give each kindle a unique key and drm files to one kindle only before they send it.... I suppose that would allow emailing files but then the same files wouldn't work in kindle for pc software, a second one would have to be emailed for that....
My point however was emailing a drmed file and also means to read the file put both halves of the drm right in the greedy little hands of the consumers. Publishers wouldn't like that. Not that I'm sure they like anything.
