This is an awsome plugin and is almost exactly what I am looking for. One thing that I would like to see and suggest is a way to have it draw out the gpx track and show the specs of the track (distance, speed, time). I know it is possible as I saw it done on a few other sites and have implemented it on a basic scale. But I am new to WordPress and haven't looked through all the module creation tools yet. I took a quick peek at your files to see if I could integrate the other tools, but my PHP skill is not that strong.
