Cheap technology and advances in publicly available navigation systems until recently too expensive for any but military... spells boom in the making.

The trouble I see is the industry will develop faster then lawmakers can keep up with. I'm sure many were waiting to see what FAA and FCC would do. Which turned out to be extremely lax. Basically leaving the door open.

While terrorism and zombies are likely to grab all the headlines. I think following the money would lead one to banking and insurance industries quickly.

I'm not against tech in general but am cautiously optimistic as it invades our everyday lives.
