How to watch my Nikon d7000 video feed on a computer?

I want to see my video feed live on the computer so that I can check focus without an additional monitor. I know Canon can do this, but can Nikon? What software do I need?

It's called tethering and you may be able to find such software either from Nikon, not really likely,
or do some research here.
