Is there an in-browser, Flash-free method to view ebooks from Adobe Content Server?
We currently offer a library of c.50k specialist ebooks via a feature-rich "ereader" web-app (HTML5/JS based with various fallbacks down to IE7).
However, management want to be able to offer "downloadable" ebooks for "mobile devices". By this they mean a file that the user can download and read offline. Adobe Content Server is fine for this (if a little expensive, and a little hated by the users, but unfortunately it's becoming an industry standard...)
OK so if we adopt ACS, making downloadable-for-offline-reading a possibility, what are the options for online reading, assuming we want to use ACS for everything and not just offline? In other words ... is there an in-browser reader for Adobe Content Server?
Flash is not a possibility as a) a lot of the users us iPads (yes for online reading too) and b) a lot of the users have to use IE7 with no Flash installed (the NHS is a major customer).
I realise I might be asking for the impossible but I thought it would be worth hearing peoples' thoughts.
Please don't advise me not to use DRM, it's not my choice and I have already advised against using it. However we are contractually obliged by our suppliers to have "a DRM solution" for offline reading.
If there was a widely-available alternative solution to Adobe Content Server I'd be interested to hear about it. I have already integrated ACS once (version 3) and don't really look forward to repeat the experience...
