Well - not a LOT of response on here (in spite of this post being read a bunch of times)... but that's okay. I didn't test the open-type features (character replacement) in OpenOffice, but since it's less restrictive (in many ways) than Word, there's a good chance they're working.
(I'll just regurgitate here what I also posted elsewhere.)

By the way, there's a .txt document within the .zip file that explains this, but it's probably worth mentioning here:
The font only uses its basic characters within MS Word (and perhaps other word-processing software) because it doesn't have a digital signature--something that is required by Word in order to "safely" use Open-Type font features. However, InDesign, PhotoShop, and other design software should automatically use the full effects of the font--which actually makes a pretty big difference in how it all looks when everything is displayed--provided open-type/ligatures are enabled within the program. I believe most of enabled by default.
