[Q] Is a rear facing camera mod possible?

view story

http://forum.xda-developers.com – As many have noticed Asus left the mount for a rear facing camera inside the nexus 7 even though they later took the camera out. My question is, what would it take to install a camera into that mount and get it to run? My guess is all it would take is the right camera and a connector that could be installed into the board beside the camera mount where the old connector was. Of course a hole would need to be cut into the back cover which may interfere with the nfc antenna. Or would it? Would the firmware of the device need to be messed with, or would the camera work with any camera app like nor (HowTos)
