I'm also interested about this (or very similar) out-of-band channels in real-world applications. Using the LED OOB-channel could prove to be a reliable way to manage the devices, and maybe even to exchange security parameters. If there was a protocol, it would help in exchanging different kinds of information (short POST-like codes vs. whole shared/asymmetric keys) over the air. This also brings me to the question of how much this list will touch into management of security, i.e. bootstrapping of security associations, setting of access control rights, etc. Regards, Johannes -- Dipl.-Inform.
