IMO, additional permission isn't needed -- it's common knowledge that people save stories onto their hard drives and/or print them. This is simply something an author has no control over once they post to Ao3, LJ, or anywhere else. Even if an author "opts out," they can't stop me from simply copying and pasting their story into my .html template and converting it for my Kindle (for which there are instructions on kindledfans and elsewhere), any more than they can stop me from printing, or saving to my hard drive. It seems to me such an opt-out could do more harm than good by creating a very false sense of security. I don't see that making conversion easy makes things different, as long as the end user understands they absolutely cannot repost the .mobi or .epub files elsewhere without the author's permission, any more than they can repost the story in html.

That aside, I would be happy to act as a tester for you for any Mobipocket files on whatever you end up doing. I have a template I use with some very simple css that formats stories for Kindle pretty nicely. I'm sure we could round up some other helpers at kindledfans as well.
