1. How about a plug-in architecture to the VM which takes code specifically designed for graphics primatives which have been put in the code. The idea of plug-in is a lot more fine grained than what you're saying.

2. LISP is a great example. It is the first example that people present. Ashame that LISP has such terrible syntax. Wouldn't it be nice to have an editor that displays code at a higher level, but the low level language is like LISP. Putting code in a different form allows that. I'm looking at doing a language in Argot ( http://www.einet.com.au/ ) which is binary. It will probably act a lot like LISP but will look like a format that the user is comfortable.

3. I disagree. Grammars and parsers are a pain to write. And grammars are especially hard to develop and get right. A format which is closer to AST is easier to parse. If we're going to get rid of this tower of babel we've developed for ourselves, we need to develop more flexible formats to describe code.
