T5 : How to get a Page in a Dispatcher ?

[Steph]

Hi all,

I have implemented a Dispatcher based on the wiki solution provided by 
Chris Lewis in order to check the authentication of the users on several 
pages of my application.
But instead of check the access rights of a user based on the URL, i 
would like to check it against the Page instance (say on the presence of 
a @Private annotation put on the page).
Has anybody a clue to get the page instance in the dispatcher ?
Thanks in advance.
