  Yeah - links always have 777 permissions thinking about it.  But what 
the man page for chown says it that you can prevent dereferencing at 
that point, so I would have thought you would be able to change the 
ownership of the _link_.  Not that this is something I've tried.

In fact I suspect that it is best to follow the rule that, once linked, 
the link _is_ the target. So that would mean it is the permissions (and 
ownership) of the target you want to change anyway. Would it not be the 
case that if the user can't touch the target directory then they equally 
won't be permitted to remove the link?  I think that's how it works but 
I don't have time to test it right now.
