Yes yes yes yes yes - I've said in a couple of posts as well about ACL's, but it's been a silent argument : )
Definitely a GUI integrated thing - possibly a kpart? I've heard of admins using samba on files servers so they can have any form of sensible permission management at all, as rwxrwxrwx is still remarkably primitive.
Unbelievably primitive actually. In fact, I COULD go so far as to say, mindlessly pathetic in a dysfunctional and terminally retarded brain dead windows promoting suicidal way that couldn't be thought of as anything other than a deliberate way to cripple uptake, force administration time over adoptable levels and was created by some dribbling mental amoeba that forgot to wet the piece of cat shit it uses as a brain before thinking it up, only to be out shined by a zombie community of undead technological stone age discards that see no need to get rid of it ...... but I won't say that as I might get flamed : )
