Not just what repository, but what clone of the repository! It's explained  
in http://hginit.com/05.html. The number only makes sense for the clone of  
the repository you're working on right now - basically you can't tell that  
number to anyone, because it might mean something entirely different for  
them.

I think you need to take some time and think about it. It's impossible to  
use a global incrementing revision number with any DVCS! In fact, I dare  
to think that Hg having revision numbers is a stupid mistake that tries to  
make SVN users comfy, but will only lead to confusion and angst when  
people try to refer to revisions by their "number".

Um, what method is that? Also, saying that SHA-1 hash collisions are "very  
rare" is a bit of an understatement.
