I believe you are correct that embedding a font in a document (as opposed to
printing or displaying a document using a font) would create a derivative
work.  However, my understanding is that PDF was created to finesse
exactly this problem.  If a required font is missing in a PDF document,
Adobe Reader will render an approximate replacement font on the fly
using a multi-master font such as Adobe Myriad.
