Absolutely. I was referencing an earlier comment from Kai-Uwe regarding the engineering of something that is not cross platform, only for Linux. I was assuming the solution would definitely be other than Win/Mac, but if it's also going to be Win/Mac then at least on Mac OS X there's another consideration which is that this has already been done, "simply" subscribe to the service.

No, it originally depended on WinFS, but since that was killed, the variable location of profiles was shot down and still all are expecting in a single directory. So a whole bunch of stuff regarding WCS got really paired down to just transforms, and the profile management stuff is still all done by ICM. If ICM encounters WCS  profiles in any profile in the chain, then the entire transform is pass off onto WCS. Even for legacy apps that only know of ICM calls.
