The specifications on that site are not sufficient to build a compatible decoder. It's kind of like providing a schematic diagram with a bunch of the values left blank.
There would be reverse-engineering required, which kind of goes against the ethos of amateur radio? 
Everything we do on amateur radio bands should be openly documented (whether in specification, or worst-case, as source code) to allow others to experiment freely.
Operations on ARISS, being worldwide and trying to reach out to as many people as possible, should be leading the way on this front...

Well, I suspect whoever organized the experiment was likely more familiar with KG-STV than the alternatives.  Let's celebrate the fact that a digital format is being tested, even if it won't have error correction turned on for this first experiment. 

While the KG-STV format is not well specified it does not seem to be proprietary - lots of details are on http://www.g0hwc.com/kg-stv-english.html .  If it becomes ARISS 2.0 standard, I imagine software will present itself for non-Windows platforms.
