He would be talking about the bluetooth receiver charging base that
comes with the MX900.  It proxies Logitech bluetooth mice and keyboards
as usb devices.

I use my MX900 and Targus mice in both FreeBSD and Windows XP.
Rebooting back an forth doesn't break the connection to either.  I would
guess that the MX900 is sensitive only to the hardware address, since
both OSes use my notebook's internal bluetooth receiver.

I have found, however, that something does get broken if use bthidd with
Windows XP hibernated.  When I bring Windows XP back out of hibernation,
I have to have the machine search for devices to clear the stale
connection, then push the connect button on the mouse, search again and
manually reconnect the mouse.

The MX900 doesn't support pin-based pairing AFAIK.  It "auto-pairs" by
remembering the last host to which it was connected and restores the
connection whenever the host shows up.
