I just use the Microsoft WEFT Tool to generate EOT fonts. It will convert any TTF to an EOT and encode it to work on your website. Remember EOT have domain usage information so people can't steal your fonts.
I am using EOT an the font-face with
http://www.defense.io and WHMCS Smarty Templates. I am using 2 fonts one script font for headings and a nice font for body.
