Say you were tasked with coding a design that used non-standard web fonts, how would you go about it?

A non-leading way to get them to talk about @font-face and how it works. Talking about how it works as a core CSS technology is great, as well as talking about services that provide the fonts and can make it easier e.g. Google Fonts, Typekit, Font Deck, Cloud Typography, etc.
Bonus points for obscure knowledge like the history of @font-face syntax or Firefox's issue with cross-origin fonts.
