It looks like the FAA has brought down the ban-hammer on commercial use of drones. At least for now.
The reasoning behind this appears to be that they are treating them as "model aircraft", which are only allowed to be used for "recreational and hobby purposes".
I've got no idea how the FAA processes work but this seems like the sort of response you might get from a jobsworth rather than anything forward looking. I don't think it precludes rule changes at a later date but it simply seems to clarify the rules as they are.
