I could use the tangent angle at various points, or lengths,  along a
path. This would be used to both offset and align elements along a
path at the same
angle as the path at various points(or lengths). e.g.
var tangent=myPath.getTangentAtPoint(x,y)
or
var tangent=myPath.getTangentAtLength(length)

Is this possible with current SVG? Also, does anyone else see the need
for this as a DOM interface?
