This does not appear to namespace the branches and it looks like you have
to edit .hg/hgrc for each remote that you want to track. It is quite
different from namespaced branches/bookmarks. I guess that's what you plan
to work on implementing.

Sounds like this has come back to the old argument that branches/bookmarks
aren't a useful feature and that separate clones should be used for
everything.

Barry pushing to his own fork was fine for this case, but I don't buy the
argument that clones are a viable replacement for branches. Even Mercurial
concluded as much by hg-1.6 when they added pushing and pulling bookmarks.
