This is very interesting.  However, playing devil's advocate, I see two 
serious problems with svg for web pages.

1.  Complex SVG files are huge.  Those node and fill definitions get 
massive in a hurry.

2.  Complex SVG files are mega-cpu intensive.  Everytime you try to scroll 
the page, it shuts down your computer for x seconds to redraw.

But, I definitely do like the concept.  I've talked about this before, but 
try http://www.zeni.net/trf/mgspec/157.php for scaleable graphics.  I 
generate a libraray of jpgs with different scaling for the most common 
screen resolutions, although the user can plug any "zoom" value that he 
wishes into the location bar and the server will choose the closest sized 
image and scale it for you on the fly.  Php is your friend.

Yes, these catalog page background images start out as vector but they are 
mega smaller when scaled and converted to jpg raster.

On the other hand, experts have been telling me for years that the whole 
world will be using broadband by Tuesday.
