update 2012 01 18 12:45 GMT +1: I have realized only now, reading the comments, that there is one more reason after Francesco’s outburst that isn’t immediately clear but makes certain replies a bit less valid. Unlike what happens with lots of successful FOSS products, Francesco’s software is something that is absolutely useless outside Italy, even if it were localized, so his market is much smaller than that for something like Linux, apache, etc… simply because he implements specific procedures that only exist, in that format, inside italian schools, because they must be compliant with italian laws etc…
