Even though I'm still gnome-shell impaired (waiting on 3D support landing for my Radeon video card), I helped out Giovanni Campagna into getting Bluetooth support in the gnome-shell.
My work was to review Giovanni's code for gnome-bluetooth, and making sure that the gnome-shell behaviour matched that of the existing GNOME Bluetooth applet.
A lot of to-and-fro, but the gnome-bluetooth changes are now in, and waiting on sub-menu fixes for gnome-shell itself. Owen was kind enough to provide me with a screenshot for your enjoyment.

Bluetooth in the shell
This wasn't my first interaction with Giovanni, as, in another long-winded bug, we hashed out the volume control shell icon. This work is already merged, and lives in gnome-shell.
