What ever they do to stop peer 2 peer, they may get a bad image, upset the buyers, but they can’t get between each peer ! : Lalala .
Well in fact it looks like Sony could do “more” illegal stuff than you and me to control the copy.
A friend of mine has been developing a web site to exchange stuff for a local group of friends.
I have listen to a Security guy at Apache (Larry Wall ?) about DRM and it is frightening. The point is that the definition of what a “family” or a “group of friend” is would be decided by Sony and other DRM guys. Not anymore by the layer and the “official justice”.
