There are several people who were instrumental in helping me get this book completed. Most important was my editor, Jim Sumser. Jim was extremely encouraging, which was important because of the aggressive schedule that I wanted to follow. He also really helped me organize and present these (often scattered) ideas in a rational way.
I'd like to thank my technical reviewers, who each pointed out more than one serious blunder. Andre Paree-Huff made a number of encouraging comments about the book. Ian J. Brown, CCIE# 3372, showed his vast depth of technical knowledge in his comments, which allowed me to make significant improvements to the quality of the information presented. And Scott M. Ballew offered many important structural, as well as technical, suggestions for which I am grateful.
In addition, I'd like to thank the following people at O'Reilly: Sheryl Avruch, Mary Brady, Claire Cloutier, Emma Colby, Tatiana Apandi Diaz, Jeffrey Holcomb, Mihaela Maier, Jessamyn Read, Ann Schirmer, Ellie Volckhausen, Melanie Wang, Rachel Wheeler, and Sue Willing.
And, I am particularly grateful to Sherry Biscope for her unconditional support and encouragement throughout this project.
