An amateur/educational group called Quest For Stars plans to lift a glider to the edge of space with a balloon to film the last Space Shuttle launch. In future flights, the glider will be then released and navigate home, broadcasting FPV video the whole way. It appears that they're using standard Eagletree and Rangevideo gear, including the basic Rangevideo return-to-home autopilot.
Here's their description of the project:

Everything minus the airframe and ballistic recovery failsafe will fly on our July 8th launch. We have designed a ballistic recovery method to return our UAV to FAR 101 parachute flight as a failsafe.
Our July 8th flight will TX 1.2GHZ FPV down from the heavens live during the launch of Atlantis STS-135. Anyone within RX range will be able to see what our nearsat will see. We are trying to get eagletree and rangevideo to provide additional demo gear that we can loan to the local news media so they have a feed for rebroadcast. On that same note, we are also looking for local FLA volunteers to recieve and stream the video over the internet via ustream. That way you all can watch FPV history live as we see the SpaceShuttle zoom by!
