Why not use subclassing? A few days ago, I attended M-J.D.'s talks in
YAPC::Europe in Paris, and in one of them he just advised something
like that. You do not play around somebody else's namespace,
you reuse it to make your own namespace. When you remove all
the buzzwords, OO is just a few good ideas, and subclassing
is one of them.
