Writing a book!

I have been given a great opportunity to write a book. My employer is giving me the opportunity to implement enterprise-level software using Ruby on Rails. I am very fortunate to be a part of this plan. Rails is new and exciting, but needs to be proven. We need to prove concepts like REST (representational state transfer) can work running a multiple million dollar operation. We need to implement a distributed database. Most importantly, we need Rails to work with legacy systems and data. This book will be a practicum of sorts, chronically the entire process from bidding the system to the client through to the "maintenance phase".
