i have just seen the release of the new Sony Cameras for Smartphones (QX-10 + QX-100) - isn't this almost what we would need to make the perfect camera for a copter ?
Remotely controllable Zoom lens, along with a Photo and Video function ?

Here is also sample code for Android..
How about just placing a mini android PC together with the cam on the copter and downlinking the video signal from the mini-PC ? - So far, i have only found HDMI mini PC's, but maybe there are also ones with analog out ?
Sample of such one is here:
What do you think about such a camera video / photo solution ?
