My bad, that was for a tree-ful branch.  For a new treeless branch in a 
shared repository with no additional revisions, I get 20KB::

nmb at guttle[/tmp]$ bzr init-repo --no-trees bzr
nmb at guttle[/tmp]$ cd bzr
nmb at guttle[/tmp/bzr]$ bzr branch ~/src/bzr/bzr.dev
Branched 3513 revision(s). 

nmb at guttle[/tmp/bzr]$ bzr branch bzr.dev bug-1234
Branched 3513 revision(s).
nmb at guttle[/tmp/bzr]$ bzr co bug-1234 work
nmb at guttle[/tmp/bzr]$ du -k bug-1234
0	bug-1234/.bzr/branch/lock
12	bug-1234/.bzr/branch
0	bug-1234/.bzr/branch-lock
20	bug-1234/.bzr
20	bug-1234

That's 50 branches per megabyte.  Seems like plenty of density to me. ;)
