Blogs Widget in Admin Sidebar

Anybody have suggestions on how to get the Blogs Widget to show up in the admin sidebar?

I need an easy way to switch between the backends (admin) of several different blogs. Would love to have a list like the one in Blogs Widget that I could just click on and switch sites. Extra points if I can stay on the same page of the backend while going to a different site.

For example, if I am at http://site1.mydomain.com/wp-admin/themes.php, I would like a widget with links to:
http://site7.mydomain.com/wp-admin/themes.php
http://site3.mydomain.com/wp-admin/themes.php
http://site6.mydomain.com/wp-admin/themes.php
etc.
