Mozilla peeps, is it conceivable that this could eventually get into firefox, or is it not the right fit in some way.

There was a recent discussion about map rendering and I commented to "just convert to SVG and let the browser render it" to which someone said that's too slow, to which I said "so improve the browsers vector rendering" rather than do a high performance renderer just for map software.
