Now this really gets to what was eating at me.  My traces are very dense
in places where I was moving slowly (under the speed limit :-)

I was wondering if there was some optimisation occuring to remove points
that were on a straight line to reduce the density and prevent bloating
of the db.  If there isn't then, like you say, I will need to edit the
xml file by hand?  That sounds pretty boring and error prone.  I might
try to modify JOSM/add a plugin if that's the case.

If I upload a trace for an existing road in to the OSM db, is some code
there going to average my results in to the db?

I'll try and collect all my newbie questions and answers and maybe they
can go in the wiki?
