Hi, Marcel

Thank you for your kindly reply.

I am starting to look at the D-bus framework and passkey-agent.c in
utils/daemon/.

One question regarding the bluetooth applet, maybe it's a little bit stupid.
But I really I can't figure it out by myself.

In my program, I prefer the user enter the passkey from the terminal rather
than from the applet window. I afraid I need to disable the bluetooth
applet, since it always automatically jump out a window when it finds
devices requesting pass key.

The figure 1 presented in "Security interface" shows the applet was built
upon the D-bus. Do I need to do some changes on gnome/applet? Or just modify
the passkey agent.

Please give me some hints on how to disable the applet during the
authentication.

Many thanks and Merry Christmas,
Jason
