Yes, I think this would be an acceptable solution, especially because if you, as an author, licensed a font from a font foundry - both you and the foundry would be "in the same boat" on this. Font foundry wants their IP be protected from misuse (hot linking), while you, as a licensee, want to protect that IP to satisfy your license conditions. However, this has nothing to do with using a particular data format, and can be used with any font, be it raw or EOT with empty root string. And, this mechanism would not address the other concerns relevant to raw font use. If I get a URL that looks like http://your_domain/fonts/coolfont.ttf - I can click on it and "Save file as" dialog would pop up - the referrer value wouldn't prevent it. Raw fonts can be saved directly to my "Fonts" folder - this is why font foundries don't want to allow raw font use. Regards, Vladimir
