[OSM-talk] Drawing only using ways (getting rid of segments)

[Nigel Magnay]

*sigh*

The point is to show how you can do away with segments. Ignore the other
database stuff. Since we can't even agree on segments not being needed and
that ways are an ordered list of nodes, I hold out little hope of anything
else being implemented. Nobody can even agree what license to use.

There's been traffic about db format on the dev list. Spatial indexes may
help. You don't need postgres or any particularly clever stuff to vastly
improve the major use-case (tile serving and caching).
