Hi Tom and all,

Yes, the cost of adapting the infrastructure and maintaining
the databases is what crossed my mind too. Given the rational
arguments that you expressed (after filtering for venting <g>),
what would you consider the best directions for research in
order to make a dent?

Would a more self-contained system that does not depend on a
very detailed geographic database work any better, such as
having "only" regular GPS (as used also by the sighted) plus
local obstacle detection via camera/sonar sensory feedback
to deal with "changing local conditions"? Any other ideas or
suggestions?

Best wishes,

Peter Meijer
