I thought this was really cool, until I saw that it cost $129.... Realistically, who would buy this? I'm assuming that because it is proprietary, it can not be used on the Internet, and if you don't have to cater to arbitrary OSes, why not use grh software?
I am a type nerd; I've bought my share of typefaces in my time. This offers no discernable advantage over traditional chart generation. It only makes sense as a web font, and even then, it's a hack. I just don't see it worth the money.
