I don't know much about e-reader formats, but Calibre 
(http://calibre-ebook.com/) can convert various file types (including 
ODT) into various formats used on e-readers (EPUB, MOBI, AZW3, ...) So 
far I've only used it to convert a few files to view on my Kindle, so 
not sure about support for adding encryption / DRM, but it might be 
worth a look as a starting point to modify or just for ideas.

Mark.
