That's very interesting, I had no idea that the Inria was doing work in this area.

We have done work to develop SVG-specific codecs within BinXML. These allow us 
to attain better compression levels on some parts of SVG, for instance on paths.

One interesting part of that research lead us to create lossy compression codecs 
for SVG paths. I know that the idea of applying lossy compression to vector 
graphics is a bit weird but it does in fact make sense in some cases. If you're 
sending a highly refined drawing to a device that has a low resolution, you can 
lose a good deal of precision on the points of your paths before it will make a 
visual difference, and it does give better compression. I will very probably be 
publishing a more complete description of this some time after our next release 
is out (ie tomorrow if all goes well).
