you can include the font file and refer to it as a relative path. I DON'T think that loading fonts from a zip file are working yet though. If you unzip the skin does the font work?
ALso, you can put FREE, PUBLIC DOMAIN fonts in your skin, but not the ones that come with windows, as those typesets(font is actually the word to refer to the size of the text, improperly used in society today) are copyrighted.
And On that day, the Lords of the land said unto their Master Architect, "The temple you have made to the gods of Wasabi and Maki has brought us no great prosperity" and they sent out him into the lands.
As he traveled to a far off land, he found he wasn't traveling alone, but that he had gained companions, and when they found their new land, they started work on a new temple, one that would be OPEN to all who wanted to worship.
from The Book of Wasabi C 12 Vs 09 (pg 2003)
