Hi Marcel
My hcid patches with support for Dbus, extended configuration files
etc. are available here: http://noring.nocrew.org/bluetooth/
The patches are made for Bluez utils 2.4. I guess some work is needed
to match the most recent release of Bluez utils.
The Dbus interface could be improved. Perhaps it's a good idea to think
about how to include interfaces for SDP and other services as well in
some kind of general "bluetooth" interface?
