Getting around the world

this document is just an introduction to the subject, and therefore it is in a “bullet list” format, with a main issue introducing each bullet list.

it was presented on 2008-09-28 (WGAW Registered) as a proposal for concept for a chapter on “social networking: security issues”, as part of a wider book on “network security”, but eventually I had to withdraw from consideration my concept.

my original material is published here, with some limited changes, due to the evolution of the subject, and to make this posting as self-contained as possible.
