[OSM-talk] Multiple Layers for OSM

[Serge Wroclawski]

Everyone (including me) has this idea every few years, especially your
second idea. Then they start coding and the problems begin to really
come to light, especially when it comes to reconsiling editing issues.

I think this is one of those "it doesn't help to talk about it",
problems. Code, find the problems, then take a stab at fixing them,
then discuss better ways.
