I cam across this article in the Guardian on-line version. http://www.guardian.co.uk/uk/2008/jul/21/civilliberties.privacy
And noted the software is available in SL - can you track an avatar by bluetooth???? I am impressed - does that put the Big Pond sim in Australia, Dresden Art Galery in Germany and Knightsbridge in London - cos Hypatia must have clocked up a few million miles - and can I have those airmiles for Hypatia's avatar (the Keyboard Godess) who would like to go to Melbourne!
On a more serious note and having listened to Steve Gibson on Security Now (A TwIT podcast - have they thought about renaming that acronym) the tracking of not just your person but your internet behaviours, personal location and the views you express (Hey! I blog, therefore I am fair game) are very much up for grabs by the sneakyist technologist. Be very aware Big Brother is not just watching, but listening and reading - though what he may deduce from all this information is..... I imagine steam will come out his ears and his head blow off actually.
