@mubertmumphrey: Note that you should be able to use the OTF directly. Just rename them. (I'm using some OpenType CFF fonts without any issue right now)

. They should be a bit sharper and less fuzzy if the hinting is good. But it depends on how you prefer your fonts to look, sharp or fuzzy

.
@no1bossman: There is no tethering until you atually start it yourself, that's what I just said.
