BP Style menu Bar

Ok, wierd one here, but what i am looking for is to have a bar running accross the top of all sites and pages in my Mu site similar to the Bp bar.
The Bp bar is everymuch designed to assist a member of the site find groups and blogs etc, and create new blogs.

What i am looking to do is have a bar like the BP bar, except use it for navigation. I'm using Mu as a CMS type system, and thus each blog is actually another catagory. So a single bar accross the top with the navigation menu that is consistent will alow my users to always find the catagories of information that they are looking for.

Any idea on a mod that does this? The adminbar is far too focused on hosting blogs for my usage.
