do you plan to implement some kind of online viewer/reader into the calibre server part?

I recently showed a family member "how to read ebooks" and she missed having at least a preview, although, also downloading, saving, opening in an offline reader is too much for the not so technically inclined, so it would be a cool thing to have an online reader, which saves the reading position in a cookie, so that the whole reading process can happen in the browser.
