embed a flash window in a mini-panel

Hi there,
I'm wondering how to include a given 'page callback' (not the menu items!! - the page content should displayed) in a mini-panel, because I like to use the tab panel style look for it. Or what about a iframe..
Is this possible? The page callback runs on ...http://mydomain.com/avchat3 .

Any ideas?

...
$items['avchat3'] = array(
    'title' => 'AVChat Video Chat (User)',
    'page callback' => 'avchat3_userinterface',
    'access arguments' => array('access avchat3 user interface'),
    'type' => MENU_NORMAL_ITEM
  );
