I'm with the "Keep it" fraction. Especially the ability to access every 
single font property in the Javascript DOM is extremely tempting; not 
for long texts or even books, but for something, that could be called 
"multimedia font". Such a font could, e.g., interact with the user at 
runtime, which is almost impossible with OpenType (apart from 
manipulating OTF features).

Cheers,
Manuel
