On the other hand, it might be nicer to think of a way to do it that
works with multiple underlying protocols. The whole point of Yadis is to
allow a big bunch of different technologies to work together in a
loosely-coupled fashion, so unless it's really the only way to go I
think it's best to avoid piling new stuff on top of a particular service.
