Below my post about Chrome's sandbox I engaged in a discussion with AlienRancher regarding the function hooking (or 'interception' as Google calls it) really being a security mechanism. I must confess that I really thought it was, and I even liked the idea. But in fact it came out that function hooking is for compatibility purposes only. If a plugin has trouble running in a restricted environment due to problems with limited access to some keys/files, the hooking mechanism can transfer the calls to the browser, and they will be done with browser privileges (of course if a certain rule allows it).
It means that my hook taking off PoC was still OK, but not really needed for anything ;>
Sorry for misinterpreting the whole hooking mechanism then ;>
