The CSS3 @font-face spec contains the following example:

@font-face {
  font-family: Gentium;
  src: local(Gentium), url(/fonts/Gentium.ttf);

The standard says that this would use the locally-installed font if
available, otherwise the font from the URL.  So the rule in our case
might look like:

@font-face {
  font-family: "High-Quality Font";
  src: local(High-Quality Font),

In fact, the font filename and the name embedded in the font file
aren't used at all in CSS, AFAICT.  The standard gives examples like
this as well:

@font-face {
  font-family: Japanese;
  src: local(HiraKakuPro-W3), local(Meiryo), local(IPAPGothic);

The mangled font name could contain the original font's name, so that
authors can keep easy track, in addition to the license warning (as I
illustrated above).  It will still be impossible for users to use the
font without realizing they're violating the license terms.  The only
disadvantage to authors that I can see is that the names would be long
and look ugly, but I think that's really a very minor detail.  You
could even have your program auto-generate the @font-face rules, if
the author gives the URL to the folder he's putting the font files in.

Why do you suspect that?  From reading the standard, it seems like
you'd specify different font styles and weights just as for any
@font-face.  @font-face completely ignores the filename and any
embedded naming metadata, AFAICT, so to the author the only difference
should be what URL they have to put in the src() rule: that's the only
place it makes a difference to @font-face.  I don't think this would
be a noticeable additional burden to web page authors, as compared to
