The reason I ask is because PaulB has loaned me his SpyderTV calibration tool for testing. It's a colorimiter very similar to one used in Colorfacts, and I've been testing it alongside my own Colorfacts colorimeter. It's designed for direct view displays but with other software can be used for projectors. I used it to set my monitor to 6500K (I don't think there was a D65 option on thos particular software), and then measured it with Colorfacts. The CF Trichromat-1 sees all displays (direct or projected) accurately as far as I know (there was a glitch with fresnel lenses in the past though IIRC), so I took some readings from my PCs CRT monitor and compared it to the TR-1. The readings are so close that I feel the SpyderTV can be used for calibration to within 3% accuracy of D65 - ideal for home use IMHO. The only unknown is whether or not a front projected CRT produces a similar spectrum to a CRT direct view tv or monitor. I don't see why not but thought I'd ask and at the same time see what interest there is so I can post the info necessary for you to get it working for your own pj, along with some comparative data so you can see how close it was to Colorfacts so you can make your own mind up.
