Could this be used within email messages? I know that some CSS is allowed in emails.

  The short answer is probably not, for the simple reason that CSS and HTML support in email is generally pretty poor. Most webmail clients rely on having to rewrite CSS (for obvious reasons), which means that properties tend to be on a whitelist rather than a blacklist, and I think @font-face is usually not on that list. For many clients, there is also hopefully remote resource load prevention that prevents it from working.
