That's beautiful vector work. I'm copying this to the dev list for reference

Wow, I was just going to ask this as well.  Have recently been in touch with
some of the dojo people, specifically the http://openrecord.org people.  We
were chatting about integrating GIS functionality in to it - they have a
number of ways to display data through charts, and on a map would make a lot
of sense.  OpenLayers is an obvious choice for that as both are pure
javascript.

Their vector support looks quite nice:

 > The new Dojo 0.4 release includes a dojo.gfx 2D vector  > graphics
library, which renders natively to browsers as SVG or VML  > (which means it
supports both Firefox and IE, as well as others).
 > Having the new dojo.gfx library should make it fairly easy to write a  >
tool that would let a user draw lines and shapes on top of a map, and  >
then pan and  zoom those drawings whenever the user pans and zooms the  >
map itself.
