that's a big "if". I assume that the purpose of an object's ID is to  
be unique. This cannot be verified by a single user, IMHO. The closest  
thing that comes to my mind is when Apple, when launching the Mac,  
used a  system to attach a creator to a file, which corresponded to a  
unique application. To enforce that uniqueness, Apple kept a   
repository of all four letter application signature, and any  
programmer which wanted to distribute an application was supposed to  
submit the signature for approval by Apple.

Now, of course, you can do anything you want (after all, it's only a  
bunch of 0s and 1s), but it would most probably defeat the purpose of  
an ID.

(BTW, "you" is a generic one, I do not me Mark specifically.)
