I should note that i am not necessarily against the idea of an audio  
equivalent of the canvas element, i just don't believe such an API  
should be part of the <audio> element.

That is correct, but it isn't really relevant.  The data URI scheme is  
entirely independent of the image (or any other element).  You can  
just as easily use a data URI for stylesheets, html, or even audio  
already :D

The point is that <img>, <audio>, and <video> are all designed to  
display fixed content.
