What will the customers accept?
As discussed above, there are some solutions which provide some protection against casual copying.
However, what will the customers accept?
- Reading a long e-book on screen is a horrible experience, even in the best e-book software.
I've tried many e-books, newspapers and e-courses in a variety of formats. A lot of determination is needed to read anything more than brief passages of these publications. The necessary zooming, scrolling and panning quickly become very tedious.
- Customers may well have a valid reason for reading their e-books on more than one PC; both online and off-line.
Anything which works only on a "tethered" desktop PC will be very unattractive.
The more stringent the security, the lower the value to customers so the lower the selling price.
The higher the security, the more insulting it is to genuine honest customers.
Finally, do remember the legal requirement to provide "accessibility." Under anti-discrimination laws, people must be permitted to customise their PC display. Some secure e-books prevent this.
