The code is fairly straight forward. See:
http://svn.gnome.org/viewcvs/nautilus-sendto/trunk/src/plugins/bluetooth.c?view=markup

The code first does a ListRemoteDevices (to list all the known, visible,
etc.) devices in add_known_devices_to_list(), and then runs an discovery
using DiscoverDevices in start_device_scanning().

Nothing mind blowing. I want to show all the known devices first (ie.
the ones in the databases), and then add the devices
visible/discoverable when the application is launched.

Is ListRemoteDevices actually doing anything on the HCI? I was under the
impression that it should only pull items from the disk...
