I apologize for the abbreviated post (about to board a flight in Atlanta to Vegas), but National Instruments has launched their new LEGO Mindstorms NXT website!

Per the LEGO press release:
“Learn how National Instruments (NI) and LEGO jointly developed the LEGO MINDSTORMS NXT Software, and Test Drive the LEGO MINDSTORMS NXT Software at NI.com with an excluisive online demo.

Also read about how the software that powers MINDSTORMS NXT robots is an optimized version of the professional NI LabVIEW graphical programming software. A software used by scientists and engineers worldwide to design, control, and test consumer products and systems such as MP3 and DVD players, cell phones, and vehicle air bag safety systems!”

Addition (by guy): looking in the above site I found this: 

Program NXT Robots Using NI LabVIEW
LabVIEW users can also program their MINDSTORMS NXT robots in LabVIEW. The LabVIEW Toolkit for LEGO MINDSTORMS gives existing LabVIEW users the ability to create and download VIs to operate and control their LEGO robotics systems. The toolkit also makes it possible for third-party software and hardware developers to create native blocks for MINDSTORMS NXT software.
The LabVIEW Toolkit for LEGO MINDSTORMS will soon be available for download.
