yes there definitely is some interest in doing this.
I have a very simple example of this and MathML in the
latest version of the XML package for R and S
in the Omegahat tree. That has now been cleaned up so that
it only needs libxml to do both DOM and event parsing
and contains many more examples of how to use things.

Actually, I was going to suggest an SVG driver as
a project for a student in your statistical computing class.
As I mentioned to David Nelson (the originator of the query on S-news)
it is a relatively straightforward task: provide R functions
to map XML elements to R graphics commands. There are examples
for this and MathML on the Omegahat web site and I will create an R
package of the XML library if anyone wants it soon.
