Trading virtual objects may sound zany, but it seems people can get motivated enough to kill for them, like this tragic incident.
Who owns virtual resources? Can there be rights over objects/artifacts in virtual gaming worlds and for that matter the Internet? Do we own email messages sent or received on Hotmail or Gmail? Is this really different from privacy? Is this DRM?
$9m trade revenues on eBay for such artifacts, gives an idea of the scope of the problem.
