Would it be conceivable for a TeX-variant to be able to perform this on 
the fly? That is, just as the metapost code is reached in the 
typesetting stage, this TeX-like program would fire off mpost to 
compile the drawing if it weren't already available then continue with 
the typesetting once the image was available?

In fact, wouldn't that be possible now with \iffileexists and \write18? 
(I haven't touched this stuff before, so I have no real idea, though.)

(Of course, you'd need to have --shell-escape enabled.)
