I had some similar ideas some time ago and the idea of accessing the
Bluetooth databases through a Unix socket with our own protocol is one
of my favourites. This makes you independent from the database format (I
prefer Berkeley DB at the moment) and you don't need to have database
code in the Bluetooth library. But when we design it this way, we must
make sure that we have the highest security for the link key
transactions.

Additional commands can be NAME or ISPAIRED, but I am also not sure if a
binary protocol would be better. Maybe we can use D-BUS for it.

Some other comments from me. I am not going to include such big changes
into hcid. This is development work for the new security manager or call
it device manager which is going to replace hcid.

Fredrik, would you please start a new post on the bluez-devel mailing
list, so we have a new thread for it. This is not really GNOME related
and I am not a big friend of cross-posting.

Regards

Marcel
