The way that Inkscape gets icons in several sizes is to use SVG and its own rendering.

After we get 0.45 released, I'll be working on multiImage support, and also looking at getting that into librsvg. Also, I'll be looking into more Tango name integration for Inkscape then, so things might be easier at that point.
