PunBB integration with Zend Framework : howto ?

Hi,
I really like PunBB, and would like on a new website i'm currently working on.
It's my first try with the Zend Framework and I think it's a very efficient way of building a website.
Sadly, right now, i don't see how to mix Zend Framework with punBB.

The trouble is that with Controllers / Routers and Actions from Zend Framework, my application looks like that (for URL) :
http://my.domain.com/area/article/param … arameter2/
(with URL rewriting forwarding everything to index.php)

Of course I could "take off" punBB from this mechanism, in order to have a "http://my.domain.com/forum/index.php" pointing on the punBB zone, but with this solution it would be a pain to integrate the forum in the site (headers / footers built "automatically" from Zend Framework for every URLs like area/article/params/)

So what could I do ?
Is there a way to have punBB respond to URLs like
http://my.domain.com/forum/viewtopic/28
http://my.domain.com/forum/userlist

... with integrations in the rest of the framework ?

Has someone already integrated punBB with a site built on top of Zend Framework, or another framework ?

Thanks in advance for every clue.
