Thanks, kovidgoyal, for the great answers.
On close reading, I deduce or infer that:
- I don't need to worry about font obfuscation as long as I publish with DRM.
- I don't need to buy individual font licenses as long as I publish with DRM.
I realize that point #2 above represents a legal question that may vary with the individual font. This is my first serious pass at publishing eBooks, however, and I just want to know:
- Will I need to research each of the fonts I'm using - freely available in MS Word for Mac 2011 - to ascertain their licensing requirements before publishing a book that uses them in DRM-protected form (such as on KDP)?

in advance!
