This will probably be fairly easy.

This will have to do a node lookup. We'll have to test what the performance 
impact is. But I definitely would vote for doing it.

This will have to do a segment lookup. We'll have to test what the performance 
impact is. But I definitely would vote for doing this one two if the 
perfomange impact is not too big.

> * Forbid a node with the same lon and lat.

Only if they have the same tags.
  - Same lat/lon, different elevation for example
  - same position two differnt PointOfInterest with different name= tags
