RC1 was working o.k. for us (we put some Daisy books up on our school website, accessible from our Moodle learning Environment). RC1 lacked some controls that we needed (fast forward / fast rewind). The developer has been very busy and did a complete rewrite. If you are looking for a solution to distribute Daisy books you probably liked the webbased approach like we have. So watch this project page, it will be up very soon. This new release will be called 12.04. A big thumbs up.
