I really advise anyone who does want to take it on to go the javascript route. backtracking calls to key frame calls to the code that has the settings for the animation sequence really isn't that hard most of the time. and chrome has the code for picking up calls to keyframes. though it traps them and a quick parse of the code to identify them may be a better idea than running the javascript and firing off the events and just waiting to trap the key frames.
you'll be pleased to hear i'm going into retirement for a good while. so no SVG animation for now unless someone wants to continue where i left off. this is to work on personal projects.
