I absolutely LOVE typeface.js, I use it all the time. But, I really wish it were a bit more flexible (for instance, wish it had render-to-canvas capabilities) for web app ideas I have that can't work without that functionality.

typeface rocks, converter s*cks

Ditto. It would be great if there was a method that I could pass either a canvas or canvas context to (along with coordinates) and have the text rendered there.
