Re: [svg-developers] arc and markers
Try arc.getPointAtLength .. See an example at http://srufaculty.sru.edu/david.dailey/svg/curve.svg It uses beziers instead of arcs, but it oughta be roughly the same stuff. This example only works in IE (sorry) -- I'm not sure if there is a deep reason for this or just my laziness.

David Dailey The deep reason is that is uses evt.getTarget().getOwnerDocument() instead of evt.target.ownerDocument. Here's a good reference: http://jwatt.org/svg/authoring/#asv-getters-and-setters.
