Jan, You can do it all with GWT. You can see a partial example of it here:
http://www.dtrac.us/hmr.html I say partial because that page is setup for a race that takes place in the future so there aren't any position reports to show yet. But, even without that, you can see how the time line and animation works. There is a time line (slider control) that can be manipulated manually. There is a spinner control to allow user control over the speed (forwards and backwards). There are also overlays that can be turned on and off (and zoomed into). And the main race course can be zoomed to (target images). We will also be tracking Marco Nannini in the Route du Rhum next month. You can see the tracking page for his race on his site: http://www.marconannini.com/tracking You'll notice the sites look very similar. The fact is, I did this data driven. This way, I can just add a few rows to a few tables to create a new event. It also supports multiple devices (boats, cars, people, whatever) in a single event. It's not hard to do. Brian pretty much hit it on the head when he said to use an array and a timer. Mine was a little more complex since I keep the slider, the polyline, and the position reports all in sync.
