There is an obvious security issue with global profiles, in that a global bad profile can lead to an unreadable screen. Think back to early Linux days and the problems we all had with X display drivers that left us with a borked black-screen system if we chose an unsupported resolution or our card firmware was the wrong version. For all the nuisance of the extreme lockdown, Apple and co deserve kudos for trying to make phones and pads unwreckable boxes that need no administration. One solution for global profiles might be single-boot profiles, ie. a profile is applied only until the device is rebooted. Another might be a core set of profiles for the essential system apps, thereby wiring in a safeguard. Another solution might be a form of profile which can be quickly sanity-checked before installation. I'm sure Tom with his vast experience and burning desire to see profiling extended to the industry has made numerous other suggestions and needs no input from unpaid helpers such as us.

I agree with Graeme on this issue. The use and control of application data on the mobile platforms is very different than in traditional OS situations. The available data for applications on the mobile platform is strictly "sand boxed" for security reasons, and writing of data for use by multiple applications or use by the OS is nearly impossible. Also, the hardware interface characteristics are very restrictive. A platform may have a USB interface, but it is often restricted to keyboard and mouse applications. Some of the platforms allow reading of data from a flash drive or writing to a flash drive, but the use of data from the flash drive is highly regulated. A good example of this is the image import kit for iPad. It is basically USB, but application support is limited to one or two apps and their data is basically available only to the application that imported the data.

The color management infrastructure is the same as in the "regular" Windows. I have an RT tablet in my hand and the CMS Control Panel is identical to the one in Win7.
Be that as it may, the only 3rd party Apps allowed on RT are Metro apps, and they don't have access to the full win32 API. So it's not clear if an RT app can (for instance) open a PCI host port, or set a display calibration LUT or ICC profile.
A quick search through the RT API revealed no such functions (but it's quite possible I missed something.)
