MU admin bar (not buddypress)

Just wondering if there is a MU compatible plugin, similar to buddypress admin bar, without installing buddypress.

sort of like the wordpress admin bar (but this does not look like its MU compatible)

Like the edublogs home page there is a login bar up top... but i want it to be there for front end and backend, be there across all blogs, and feature

register, your profile, login, logout, quick admin links,

is there something like this out there already without installing buddypress?

cheers
