Copyright only covers more or less verbatim copying, but not the copying
of ideas.  Patents would offer wider protection, but they are a very
controversial topic ("software patents") and out of the reach of anything
but deep-pocket corporations that can afford patent attorneys.

They can be copying ideas from this mailing list already.  I don't think
that there is any way to prevent the copying.  You would need an army of
lawyers for that.  Only big corporations can afford that.  All we can do
is to compete by quality.  The general public is becoming increasingly more
aware of OpenStreetMap and the independence from proprietary map vendors.
I hope that it is a positive feedback loop: the map is good enough for some
users, users will make it even better, it becomes good enough for even more
users, and so on.  Proprietary maps will never get accurate coverage of
minor paths and the like.  Not even cycleways, at least not here.  So, most
cyclists here should know to avoid buying maps. :-)
