Over here! I'm interested.
I would like to integrate service level security into the meta server of
kdebluetooth. At the moment you can allow/disallow connections (or show a
confirmation popup) based on the service/rfcomm channel and on the peer
device address, but we can't ask for an authenticated link. Being able to use
service level security would allow us to force authenticated links when using
any service other than obex push, which should work without having to pair
devices first.
IIRC I asked you to allow every user to send authentication requests a few
months ago, so that even programs running without root privileges can trigger
authentication. But then I didn't post it on the list as you told me, to let
other people comment on the security implications. The corresonding patch
changed only a single bit somewhere, but of course this solution is not very
conveniant. But if you want authentication to appear as a property of a
single rfcomm connection that's fine too, as long as a regular users are
allowed to use this feature. Would that be safe?

Fred
