GeoDataLineString can only hold - a line with many positions. Fra from 
interresting, when it comes to a track, there are times, course, speed, 
sattelite data, lots of stuff. So yes, I think each point need a placemark in 
order to hold all these data, and make interresting uses of them. Most outdoor 
people would probably be interrested in a replay function and data 
curves/histograms (speed, course, elevation, all sorts of more specialized 
datas - you have heart rates, I have rudder angles, depths, compas courses, 
wind data) and other analysis tools.

Unfortunately not. I suppose I could use a "scratch repository" or something 
in kde infrastructure? Git is still a challenge for me! But working with 
someone on this would be nice indeed :)
