Re: Web Fonts

I think the closest Apple API for this sort of thing is  
ATSActivateFontFromMemory... and you can activate the font globally  
or locally (where locally means it's available only to the  
application).  I think when Safari displays inline PDFs this API is  
used for any custom fonts included by the PDF, which may mean that  
Safari supports downloadable fonts right now via the use of an <img>  
tag with a width/height-0 PDF file. :)
