Integrating or sharing common NAVBAR with website using vBulletin, Wordpress & Joomla

[Fusion2]

I have vBulletin, Wordpress and Joomla installed on my website.

Obviously, i intended to use vBulletin for my forum, Wordpress for my blogging and Joomla for my articles, webpages and everything else.

With vBulletin, I created a customized vBulletin navbar which can been seen here http://southfloridafusion.com/SP32-20070422-145701.jpg

Simply explained, at the top is an advertisement. Below this is the top navbar of main menu links. Below this is my logo and to the right side is the signon screen. Below the logo is the submenu for the main menu links. Then below this are breadcrumbs.

1. Is there a way to integrate Wordpress and/or Joomla with vBulletin?

2. Is there a way to use this vBulletin navbar consistently throughout my website (ie. use it also for Wordpress and Jooma headers)?

Simply put, i would like to use this NAVBAR theme throughout my entire website. When they click on the top menu link called "Blog" the signon screen would be specific to Wordpress and the bottom menu items would be specific to Wordpress blogging menu items. When they click on Forum, it would show the signon for vBulletin and the vBulletin forum menu items etc.

Im assuming since all three are designed in PHP that there is a way. Just not sure how or where to start?
