I think the sandbox is just what the second reply said a myth, I have created a few sites in the past two years and never been sandboxed, lucky i don't know. It could just be being penalized for barking a rule or something.
I read it but have not used the method yet as none of my websites have been sandboxed. If I ever get sandboxed, I'll know what to do.
I read the same ebook that you are speaking of and let me tell you that it works. There are ways around everything if you just put forth the effort.
Google tend to give new domains a little leeway when they first get indexed. Anything suspicious though, and they show you pretty quick what they think. Sites using collaborative article spinning software to try and create 'unique' content suffer from this quite badly. If you intend to spin, spin well.
