that kind of security just begs to be hacked. And the stuff I'd want to share with folks for the book shouldnt be all that big a deal. For example, I can have people email me with the word on page x, paragraph 3, line 4 or something like that. Unless I'm being bombarded with folks wanting the files! Then maybe some kind of system might be warranted. lol In the books I always give a plug to simplymaya.com as a place I can be reached for questions, so if you or anyone else does have questions about any of them, feel free to ask here at SM!
