Plugin Request: Multisite Global Navigation

I am using multi site and I think that a lot of folks could benefit from a plugin that allows a global navigation menu. I am using the twentyten theme with the custom menu feature. With the intention of using 100’s of sites as “pages”, it would be unrealistic to create a custom menu for each individual page containing hundred’s of identical links to result in a menu that is exactly the same as the one on my main site.

I did find a solution that does not deal with a plugin, but as a novice I could not navigate my way through this tutorial’s instructions: https://dustyreagan.com/global-page-navigation-accross-wordpress-mu-blogs/

Thanks for all your help!
