what concerns me is the question if this is going to keep working or not? For some time I thought spotlight-comments-based Tags would be a solution – and later have run into growing difficulties, Quicksilver not 100% working any more with Tags, TagBot occasionally overwriting Tags, the TagBot people simply going away etc. etc.

There was SpotMeta (which, if I recall right did use a similar "Xattr"-solution ) but with Leopard that was not compatible and not developed anymore. I intend to go with Apples further development of OSX (as long as my machine is going to support this) but I want to be at least assured that the people who implement this new scheme will make everything possible to make it likely that it wil continue to work in the reasonably future. Michael didn't start fear in my heart, he just gave me a starting point to ask these questions. (By the way I have asked a similar question the Tags-people, a question based on my past experiences with tagging solutions)

Sans standards, le futur est un peu plus instable.
