Query: Wow! An amazing example of how NOT to write an IT book.

If this was an example of how not to write a book this would be an excellent book. It might be a book about the InfoBus, but any information that might be useful to the reader is buried in a morass of unreadable prose. I suggest other prospective readers wait for someone to do a better job.
