Does Salut really need .profiles? As in, is there really service-specific data - to me it seems like there aren't any different "services" at all, as you can just throw whatever you want to the local network. Perhaps WONTFIX?
Right; Salut is a pretty good example of a CM where the Protocol object should be enough.
