I just thought of something when I was thinking about shooting weddings.
It would be nice to use my d300s to shoot video at a wedding and my d700 to take stills.
The problem being that it's better to have more than one angle in a video.
The solution would be to have multiple video dslrs set up where you want them, and being able to remotely start video recording.
At present I am unaware whether this is possible or not.
It would seem that it is in nikon park as the connections on dslr are not able to communicate with other functions, like the OK button.
The simple solution to this would be, being able to reassign video start to the shutter release button.
Then I could use my normal remotes to start recording video while walking around taking stills.
