I read the last discussion about "natural"/"mapping large areas" a
little bit.

Actually my preparation was mainly based on the missing content at the
wiki. Seems to be as if I could start a some documentation of the
discussions at the lists and other ideas.

A datatype for "blurry" large areas or just for blurry areas?

Borders are also multipolygons and of the same size. So the size itself
is not the problem - or is it indeed?

A parallel project, let's name it OpenGeoMap, would neccessarily require
to merge the projects in a way that does not bother anybody.

Regarding other natural tags like natural=desert etc and borders such a
project would be a great idea.

Regarding other data types it is not a benefit I would say, because
keeping the data seperated would deny to relate them to each other.
