Not necessarily. In order to change permissions on a file you need to have write access to the directory (i.e. the special file in the parent directory that describes the files present in the directory).
To delete, yes, but to chmod? It makes no sense for that to be the case, as hardlinks would end up being a touch baffling.
Yes, you're right. Sorry. The permissions must be held in a different place (chmod isn't suid so it can't write to the directory file if it doesn't have the correct permissions) - it's a long time since I last looked at filesystem internals.
And this has drifted too far away from apache!
