doable but annoying.
I'm using ArgyllCMS spotread instead - it's not optimal at the moment, because there's no full support for i1Pro2 yet, so the sensor works in legacy mode (no M1/M0/M2 measurement conditions, wavelenght calibration and so on), but it's only a matter of time.
Commercial options are Robin Myers Spectrashop and Babelcolor CT&A.
I'm not sure, but I guess that Measure Tool (ProfileMaker) allow to make spot measurement in demo mode (i1Pro2's legacy mode only).
