Yes, if you use eWorld as a frontend http://eworld.sourceforge.net it
becomes very easy usable. But there are a lot of bugs and the Usability
isn't that good. So I would like to suggest to improve this one, instead
of starting your own project. An animated SVG export would be a very
cool thing :)

There is some work around it in SUMO (Simulation for Urban MObilitiy)
[1]. It already allows the use of OSM networks [2]. ..

Hey,
I also really like this idea. If you could spice up the OSM part in it
I think you
should definitely submit it!
Maybe you could do something with the history in OSM. What happens
if a new
motorway is opened? Or you could work with the proposed=* ways...
