I agree that Alf has done a great job in making snooks accessible - thanks from me.
Incidentally, an amendment has just made it legal to circumvent DRM in limited circumstances:
(6) Literary works distributed in ebook format when all existing ebook editions of the work (including digital text editions made available by authorized entities) contain access controls that prevent the enabling either of the book’s read-aloud function or of screen readers that render the text into a specialized format

Hopefully they'll further amend the act to allow fair usage as they have for mobile phone hacking in the same ruling. Unfortunately it might take them another 3 years. Not sure how it affects other countries such as the UK.
