It's tricky, since the traces involved aren't just the OSM ones - they 
also include Strava and potentially others.

With regard to OSM ones, in JOSM you can get information on some traces 
trace-by-trace, but it's a bit clumsy to use regularly. Traces in P2 and 
iD's "GPS traces tiles" such as 
http://gps-b.tile.openstreetmap.org/lines/15/16256/10660.png via 
https://github.com/ericfischer/gpx-updater are one-way I believe - GPS 
traces go in, but never come out.
