I just discovered something a little interesting...
As I said above, I flashed my 650 with the baroda hack to play around and test the fonts.
As I also mentioned, editing the userstyle.css didn't seem to affect ebooks with embedded fonts.
However, I just purchased another book via Kobo with it's own embedded font and loaded it on my reader to begin reading. I was surprised to find that the font was actually the one I'm calling from my userstyle.css and not the embedded font.
So, to test, I opened up my userstyle.css and commented out the... body {}... tag I added manually calling that font. This reverted the ebook back to it's embedded font.
It appears that the "body" tag brute forced the css to my font and not the embedded. What's strange is it didn't have that effect on the other titles on my reader. Perhaps because they were already there before my tinkering? Dunno...I'll need to do some more tests and reviews of the epub structures.
Anyway...for what it's worth....
