Heh, I've been away but was just going to suggest that reading your
mails..

btw a few words on security (though the scenario where somebody uses this
information and tracks you down to interfere with your system seems pretty
unlikely :)

- now that you have posted the PIN you used and bdaddr of your device, you
  might want to re-pair with a different (more secure) PIN as I think the
  link key may be derivable

- Not sure but I think that the keyboard will probably force auth and
  encryption when making connections. The FreeBSD stack does not have a
  way to do this except globally so unless you have the auth or
  encrypt flags set (see hccontrol(8)) then a remote device can
  break right in

- IMO the PIN should be ephemeral and use-once so when you are paired you
  should remove it from the config file or at least comment it out

that is probably fixed pin 0000 if not in the documentation

How is the keypress feel?  I've not had a go on one of those, but I have
an original apple bluetooth keyboard (white with clear undershell, full
sized with num keypad) that works well though a smaller one might be
interesting.
