The main problem would be to prevent copyright abuse. I guess any secure approach would require a significant time/financial investment into their system*, and any non-secured solution would just lead to everyone sending electronic copies to each other and nobody paying for it.Why do they not just post it on the net and people pay a user fee to look at it etc, instead of piblishing it ? I am sure there must be a way for a book that HAS already been translated to be available on the net ?
* looking at their Web site, it's very basic.
