I've never actually built one, but I was thinking you could probably attach a little "pod" on it with a camera, a single servo, a receiver, and maybe a GPS. This #11 camera would be perfect. You'd rig it so that moving the servo would detach the pod from the balloon. I think all you'd need is a streamer and some bubble wrap on the bottom so the pod wouldn't drift too far.
The cool thing about this is that you should be able to release the pod when you can barely make out the balloon. What limits me with my plane is that I lose orientation, but I think with one of these you could go much higher for little money.
