I've been giving this some though.

There could be a collection, similar to navigator.plugins, which is  
That collection is populated by the browser with fonts which it's host  
environment provides.
The collection could be index simultaneously by an integer, which would  
reveal fonts in alphabetical order, and could be indexed too by a string  
containing the font name (there's a case problem however).
The collection itself could be somewhat extend to have extra methods, like  
navigator.fonts.loadFont(url) which could load a font from a remote file,  
similar to the proposed behaviour for css, and make the font persistent  
and immediately available while the page is loaded, or  
navigator.fonts.disableFont(fontName) to disable a particular font and the  
browser could use a fallback one.
Each element of that collection would be an object with methods and  
properties which could give details about the font, like its name (with  
proper casing), glyph information, metrics, if the font can be bold or  
italic (or could have another style), and so forth.

That collection would be bound to a read only array in ecmascript, on  
which method like join() could be used to get a quick list of all fonts.

This can be immensely useful for any rte editor which runs on a browser.
