I couldn't figure out a way to do this so I've basically created a "Home" portal. Then off of the portal, some child portals...  like such...

www.test.com
www.test.com/portal1
www.test.com/portal2
www.test.com/portal3

Each portal has the same essential skin... just that there are three "graphical" tabs hard-coded. Each tab links to the appropriate portal eg. portal1  , portal2,  portal3 each have a tab.

This allows me to setup a different menu/options for each portal. Each tab allows the user to navigate to the appropriate portal and it's navigation appears.

My only problem at the moment, is that I would like to:
1. Use a single username/password to administrator each portal. This appears to work.
2. I would like to have a single banner appear on each portal (actually 2 of the 3). Is there a way to do this without uploading the banner to each portal? I'd love to do all of this on the "Host" level. Right now, when I try to create a banner on the host level, I get "You don't have permission to see the files on the site"... So I can't choose a banner image... Any suggestions?
