Can someone help me on the Canon Projectors.
I am told that the SX series ( also called the Realsi ) cannot be calibrated. This is (again I am told) that the projector will readjust itself to its own calibration each time, thus undoing any system calibration. I can find nothing on this anywhere else, so does anyone know more?

You can calibrate it. And all changes made by autofunctions will be stored in the menus as numbers so you can see if something has changed, and simply return the values to whatever you desire. There is no invisible parameters changed during this autocalibration which is optional.
As to calibrating I can mention that on a Mac on a DVI connection the SX60 we use provides a standard ICC profile to the Mac and it even provides an corrected 2. ICC profile corrected for the calibration you have done. Note it is on Mac only and only on DVI connection and you have to plug it in in the correct way and jump through hoops to make this feature work, but it is there when you fiddle with the setup a little. The profiles provided are not very good though so although the idea is super, the execution is not. Make a custom ICC profile with the X-Rite beamer or Colorvision product and it is very decent. I use a calibrated EIZO CG210 as my color reference and the match without said tools and calibration is not good, although it is miles better than most other stuff out of the box.
This line of REALIS projectors SX5,50,500,6,60,600 and possibly the 700 which I haven't tested are GREAT for showing pictures on and for computer use if you make a custom ICC profile. It is not great for home movie use when compared to other dedicated projectors in the same price range as it is a 4:3 chip and the black point a bit bright for a darkened room. During daytime it is quite good though. I have only read about using a ND filter for lowering the black point so I can't say it will work - but it might be worth a try to get it suited for a darkened room showing a picture show as well as the sRGB mode is with the Iris locked open, and that is a bit bright.
