Hmmm let's see bzr supports central control and FS ACL's it supports svn checkouts where your
commit cannot rewrite history on the server and cannot divert mainline history. It supports central
repository as well.
So if you want or need "coorporate theatre" and still have no pain DVCS merging choose bzr.
I'm very confused which 2 DVCS were picked? I guess git but I can't place the other one bzr, hg,
