Absolutely! As soon as someone wants to infringe on their watertight patents. In other words, don't count on finding anything that mounts on a helicopter with a pilot in it. They spent a LOT of money getting their design OK'd by the FAA and then slapping a long number of patents on that device.
We have a guy here in Phonix that has a remote control chopper that works pretty darn slick.
Hand-hold your small DV, attached to a Kenyon Gyro-stabilizer. It feels like a big bowl of Jello. You can't start and stop pans smoothly, but it maintains the momentum of any move, and takes out a lot of vibration.
