I saw a couple of bug reports in launchpad about Bluetooth pairing being
broken.  That was quite some time before the release, and I hope these
were fixed.

Last time I attempted Bluetooth pairing was in Dapper.  I had to run

  sudo /etc/init.d/bluez-utils restart

in a GNOME Terminal so that the the bluetooth daemon would inherit my
shell evironment ($DISPLAY and $XAUTHORITY in particular), and after
that it would pop up a nice GUI PIN dialog for me, automatically, when I
tried to initiate pairing from the phone.

I now that the init script was renamed to /etc/init.d/bluetooth in Edgy.
I think the PIN infrastructure was also changed to use dbus or
something, and shouldn't need the hack I had to use in Dapper any more.

I've never used hcitool cc/auth and I do not know how they work.

If you want to trick a pointy-haired boss into letting you write software in
Lisp, you could try telling him it's XML.
