Good! I will simply assume this is no violation - and continue.

To my surprise, FTManager lists both the OT TTF as well as the OT CFF. I can install both.

After rebooting the OS... I ACTUALLY HAVE BOTH FONTS LISTED IN THE MORPHOS PREFS - IN FONTS!

WHOOOOOOT!!

So looks like installing it using FTManager gets these fonts installed for real! Now let's find some apps to test these fonts with. Any suggestions?
