I think here you are assuming that you scan the box with a scanner for  
the Mac address in this case.   You're right - if the Mac address  
isn't used in the DUID for this machine, you will not be able to  
identify it by picking the DUID apart.   What I am saying is that this  
is unlikely.   The DUID based on the enterprise ID was put in because  
one of the participants in the debate thought it might be useful, not  
because we expected it to be widely used.   If it is widely used, I  
would *really* expect it to be on the box just like the Mac address  
is, because it serves the same purpose.

So my answer to this, lame though it may be, is that you shouldn't  
worry about it right now.
