Just to throw another perspective on this, Subversion handles repositories 
things in a similar way to CVS, and I find it rather handy.  Subversion has 
no concept of tags, branches, or even projects.  It just has repositories 
that have directories.  The directories can be projects, subprojects, 
branches, tags... whatever.  It all depends on how you set up your directory 
structure.  A common way to set up SVN projects is:

     /
          project/
               trunk/
               tags/
                    1.0.1/
               branches/
                    2.0/
          anotherproject/

So to create a new branch is simply:

   svn copy project/trunk project/branches/3.0

It is an entirely different model than DARCS, so I don't know that there is 
any comparison.  I do find the Subversion solution to be very clean, 
straightforward, powerful, and elegant.  We find subprojects to be a very 
practically useful idea; a project may depend heavily on a library, and the 
library may be entirely ignorant of the project it is part of.

As I said, this is just another perspective, not a suggestion.
