*sigh* The Booksense handles more formats than most of the accessible ereaders, but ePub is not one of the formats. I take it that ePub is like Daisy, and is actually a set of different files in different formats. What I can do, if I can see the list of files, is pick out the xml file and my BookSense can access those, or I can just change the xml extension to html, which most of the ereaders will play.

I don't have a converter yet--most of them convert other formats to ePubl, and what I would like is to convert in the other direction. Also, whatever converter I use needs to be accessible, and most of them are graphical. I may just end up posting this question to my LJ.
