This book was developed during the course of a trip. First, I would like to thank the many café owners who allowed me to plug my computer into a socket free of charge. I would also like to encourage the hotspot operators to create more WLAN places in the world and not to make access too expensive. A commendable example of this is the very friendly Wifirst in Paris (http://www.wifirst.fr/index.jsp), which together with the Metro operator RATP (http://www.ratp.fr/) operates an affordable WLAN at many Paris locations.
In addition, I wish to thank my daughter Isabell (http://www.isapisa.de/) and my wife Christine for their help and encouragement. I also wish to praise Skype (http://www.skype.com/) and Jabber (http://www.jabber.org) project; without these two, our communication with editorial team would not have been possible.
Alex Kempkens (http://www.thinknetwork.com/), development team member of Mambo, author of the Mambelfish component and the editor for the German book project deserve special thanks for their patience in reading the manuscript and the suggestions they made. And without Boris Karnikowski’s (editor of the book at Addison Wesley) integral strengths, you surely would not be holding this book in your hands.
Most of all, I want to thank you, my readers. Let me know how you liked the book!
