A simple UAV is not far off and I am sure they are working on it. You can bet your bottom dollar on it. It is a very interesting problem to solve. The U.S. government has to deal with subs, tunnels, and now ultralights.
I agree. A few Google searches and I can find out how to extend the rage of a AR.Drone to over 2 kilometers.[0] If they're serious about their business they're doing the same thing. Slap a prepaid cell phone on it, start up any of the popular webstreaming apps[1], and bam. You're in business.
You can fly it to a drop, check the landing space for friendly faces, and hit a back-up spot if things don't look good. Or, if you're good, just fly it into someone's back yard. It may be more costly than having someone run drugs, but at least drones can't talk (save the login and broadcast info they show, I suppose.)
And if I can think of something like this, I'd expect them to have money on actually solving their problems.
