But there is no reason they couldn't use OSM as a basis for their
tracing, rather than Google Maps. If they did, their tracing could be
incorporated back in to OSM.

Could we take their codebase, dump the data, and set it up for Oxford,
for example, except with our map instead of Google's? We could then try
to convert our Oxford map into starting traces for their system, which
could then be refined by their tools.

Would they be open to doing that? Is their code available somewhere to
download?
