ACKNOWLEDGMENTS
I would like to thank my friends and colleagues at McGraw-Hill/Osborne for their
signifi cant contributions to Home Networking Demystifi ed. Acquisitions editor
Wendy Rinaldi committed herself and the considerable resources of McGraw-Hill/
Osborne to this project. A quality editorial team, including acquisitions coordinator
Alex McDonald and project editor Carolyn Welch, wove hundreds of threads into a
meaningful tapestry on home networking. Technical editor and networking author
Craig Zacker’s creative insights are evident throughout the book. Copy editor
Robert Campbell and proofreader Susie Elkind are the best in the business.
Special appreciation is in order for all the other nodes on our home network, the
Longnet. My wife Nancy edits the draft manuscript and is always there with
encouragement. My technically savvy teenage sons, Troy and Brady, stretch the
limits of the Longnet, giving me loads of examples for the book.
