This guidebook will save users a lot of time. The information users need is now in "one place". Before today a user needed to search the Skype Forums, FAQ's, Knowledgebase, User Guides, and probably call up a few Skype buddies.

Is it complete? No I don't think so. It would be nice to see a section on VPNs and how Skype traffic is managed within a local area network.

And will it let me and others retire from our support role we play on the Skype Forum? Unfortunately not. Skype still has not overcome human nature. User's don't read guidebooks. Too bad. This is a good one.

If I am the CEO and I want Skype in... I can't use this book to convince my CTO. Thus it fails in addressing the primary question, "Is Skype secure?"

The guidebook should also deal with the security of SkypeIn and SkypeOut calls... similarly... one could comment about the security of a pocket PC using WIFI. But overall, the guide is a good step forward and like Skype itself a work-in-progress.
