Image stabilize
Predator drone image stabilize technology now available in consumer products for $50. http://www.pcworld.com/article/235129/image_stabilization_for_airborne_drones_comes_to_home_video.html

Solution to crime and piracy
UavAirframes A few hundred UavAirframes fitted with cheap $350 IMU from RateGyro and un-cooled ThermalImagingCameras streaming images over a 400Mhz WiMax link, patrolling the major Afghanistan routes will prevent IED attacks. With FpGa real-time image stabilization is done on the Mpeg4Compression stream, negating cross winds destabilizing the video image. See - Drone swarming

Anti-Piracy can be done with thousands of UavAirframes and since surveillance can be done during the day, they won't need expensive ThermalImagingCameras. With a small petrol engine they remain airborne for 20 hours, allowing them to operated from land. At a cost of R20,000 per plane 2000 drones - R40mil. Compare this to the billions of dollars in expenses to patrol and insure the Somalian coast. Fit each tanker ship at see with UavAirframes to scout in a large radius around it. If attacked by a pirate ship the drone is launched and keeps it in focus with ThermalImagingCameras and OpenTLD, allowing NATO fleet enough time to intercept the ship. Communication is via satellite phone on the drone. Use Drone swarming to attack the individual pirates if they scale the ship or on their own pirate ship when close enough. Fit a camera in the nose of a small bomb, drop it from the UAV unto a target by steering it over the video link. US soldiers would be able to overcome the insurgency this way. This can easily be done using opensource methods, but http://www.raytheon.com won't allow it.

Video goggles
VideoGoggles Link to single monocular eye piece, allows one to drive, work and watch video or work on computer.

FpGa uav integration
Openpilot can't implement the more innovative KalmanFilter algorithms at 500Hz due to the embedded CPU platform limited computational power. Use FpGa for Kalman algorithms and the CPU to handle GpsAndGprs navigation. Kalman handles non-linear effects better than the DCM algorithm. This is a significant issue for QuadroCopter drones and helicopters. For fixed wing the DCM is sufficient. With DCM to many arbitrary PID hacking has to be done for each frame.

Openpilot preferred platform
Openpilot Uses the better EKF instead of DCM. http://code.google.com/p/gentlenav/source/list Gentlenav ground speed and airspeed compensation for fixed wings must be merged with Openpilot code.

Farmers in South-Africa
Hover a quad drone above a farmers at about 20meters, with flashing LEDS. It provides immediate visuals of any situation he might be in. The OpenTLD object tracking system tracks the farmer automatically as well as wth GPS signals from the farmer. A farmer wears a panic button as well as heart rate monitor so that if shot dead an automatic alert is sent. Heart rate monitor indicates only if the heart is beating or not - Farm attacks
