I think you get the whole idea of D-Bus wrong and this is not about the
current D-Bus support of hcid for the PIN helper.

As I said if you wanna control something from your application via D-Bus
then make sure there is a D-Bus enabled pand service is running. If you
wanna do it at another level, then I don't see any benefit from it. Why
should we create another library only to help your special D-Bus daemon
if it is not Bluetooth only. In that case you should simply duplicate
the code and integrate it into your daemon directly. There is no need to
make things more complicate.

For me the only thing that makes sense if you enhance the pand with
D-Bus support and then you use that D-Bus interface in your application.

Regards

Marcel
