Tim, I'm replying off list and note that what you say is not correct. The MDSVSensor can only be used on wide-gamut displays. There is no way for a user to switch and trying to calibrate a normal monitor will give strange results.

As I understand it, it has a calibration mode for normal LCD monitors too. What it doesn't have is a mode for CRT screens. I thought I read the i1 has two modes, one for LCDs and one for CRTs. NEC replaced the CRT mode with one for wide gamut LCD monitors. Don't quote me on that though. I forget where I read it and what exactly I mean by 'mode'.
