Yep -- that's next! Shouldn't be too hard to implement the TopoFusion 
algorithm linked to from here 
http://wiki.openstreetmap.org/wiki/Average_tracks (famous last words!)

With my crappy phone GPS at least, though, the result would still be a 
lot worse than you'd get tracing from well-aligned high-res imagery. I 
suppose if nothing else though it could be a less fiddly way of creating 
something to try to align the imagery too.

Sigh -- this OSM thing would be so much easier if we had perfect 
positioning (or even WAAS).
