This should be a great resource as the HTML 5 spec emerges.

Here’s a simple example:

      @font-face {
        font-family: "Robson Celtic";
        src: url("http://site/fonts/rob-celt")
      }
      H1 { font-family: "Robson Celtic", serif }

This is very exciting news.  No longer will typographically savvy developers need to rely on clever sIFR hacks.  Oh, and not to make Internet Explorer an afterthought, but IE has supported @font-face since version 4, except with a proprietary .EOT filetype, a compressed form of OpenType, while Firefox and Webkit are supporting the more common and non-proprietary TrueType and OpenType formats.
