From 2003, one paragraph in this source reads -
A useful alternative is to embed the fonts in the Web document so that
they'll be displayed even if the recipient's system does not have those
fonts installed. There are currently two options for doing this. Microsoft
Web Embedding Fonts Tool (WEFT) lets you create font files in Embedded Open
Type (EOT) format to upload to your Web server, allowing Internet Explorer
4.0 or later to display them. Bitstream offers a different solution that
lets you embed fonts that are visible in either IE or Netscape Navigator 4
(but not 6 and 7), by pointing to a Portable Font Resource (PFR) file on the
TrueDoc site (
www.truedoc.com) or another Web server.
After reading that, I think you'll agree that this is not a good option.
