[opensource-dev] Third party viewer policy

I wonder what the official LL response would be if you gave a randomly
generated MAC in these situations, or some kind of hash from other
aspects of the hardware -any lindens wish to comment?

The other thing of course is defining what "this computer" means for
those of us who like to fiddle with our hardware. Personally i'm often
swapping components out of my desktop including harddrives and
ethernet cards.
