That is a lot of work. You will need a separate computer. I tried this and here's what I got:
A raspberry pi computer communicating with the kinect, the cRIO, Internet/Intranet (CTRL).
To use linux with the kinect, there is the library: libfreenect. instructions to get it are here:

Communicate with cRIO via i2C, from GPIO. about minimum of 10 hrs of hacking
