Hi Joe,
Ideas are very hard to protect - even patents are continuously being perused to get a slant on an idea - changed slightly and used.
If you have a good idea - produce it and get out to the marketplace as fast as possible - people are less likely to emulate an idea that is already commercially exposed.
As far as books are concerned:
Proof that you wrote the book is paramount to a successful litigation if the need arises.
"Writer Guard" [you will note I use it - see bottom RHS of the MyScribeWeb website at
http://www.myscribeweb.com ]
is a vault where you submit and register ownership of your work as you are working on it.
When you click on the seal you get the following info:
"Digitally Protected Content
This content, so affixed with the WriterGuard Digital Rights logo, is protected by United States federal copyright law.
The content has been electronically filed with the WriterGuard Creative Works Registry, thereby establishing a permanent record of this material.
The registrant of this content

I think this protection is well worthwhile.
Cheers,
Kitty.
