I presume you're referring to the Display Pro. From the
literature it has 1/3 the sample rate, and possibly other
minor differences. If X-Rite have been smart, the difference
will be in the hardware behaviour, rather than the software.

I can't be certain until I get a look at the device, but if it's a similar
OEM system to the one used in the past, it would just be a matter of
discovering the password the OEM version uses. [Some other
X-Rite devices have had a more sophisticated system, such as
the DTP22 Digital Swatchbook, and that would be more complex
to figure out.]

The password may only be in the software delivered with the OEM
device, so someone with that software would have to discover it.
OEM devices will not be as readily available, so I don't think
it's likely to be much of an issue in practice.

I'm certainly happy to add features that will aid it's use with television

Yes, I'd be interested to know what it lacks in that area.

[The most obvious problem I saw last time I looked at it, is that
most TV systems don't have LUT's. Instead they have rather soft,
ill-defined "knobs" like "brightness", "contrast" etc., which are
not really suitable for a technical setup. Various manufacturers
do seem to have proprietary (ie. non-standardised) calibration
systems for their high end projectors, but there would then have
to be custom back ends for each of these to use them in a calibration
system. At leas the Operating System access to video card LUTs is
