Forse ho trovato la soluzione in

Using the @font-face style attribute , a document can reference a font that is automatically downloaded, is used for the page only, and is discarded once the page is no longer displayed. The following example shows the use of downloaded fonts.
<HTML><HEAD>
<STYLE>@font-face {font-family:comic; src:url(http://abc.domain.com/fonts/comicbold.eot);}
</STYLE>
</HEAD>
<BODY>
<P STYLE="font-family:comic;font-size:18pt">this line uses the @font-face
style element to display this text using the Comic Sans MS font in 18-point
size and bold.
<P>
</BODY></HTML>
