"Fonts are hard."

I think this belongs as something media-mapping specific. Most vector  
formats have some way of dealing with fonts. In general they're  
either included directly or there's some established scheme of  
referencing external resources, possibly with intelligent  
substitution. But if you're putting SVG in a stream, you want to use  
the SVG mechanism, etc.

I'd also mention that alphabetic fonts are cheap, but ideographic  
(and cursive) fonts aren't, on the scale of web video.
