that is fine with me. i'm sorry this is taking so long :) now the last 
question: should we keep device specific files under /etc/bluetooth or 
just under /etc? right now i have devfs.rules, pccard.conf, 
periodic.conf and rc.conf under /etc/defaults. overrides for these go 
into /etc.

another alternative (which probably no one is going to like) is to use 
/etc/bluetooth/defaults/device.conf (defaults) and 
/etc/bluetooth/$dev.conf files (overrides).

agreed.
