[OSM-dev] Extended diffs

[Kolossos]

Sounds really a very good idea.

@Frederik: To set-up some services on this diffs I would prefer an 
OSMF-Server but at the beginning we could really start with an external 
service.

If we save time at updating the database we are able to use a more 
complexe database design (like IMPOSM) for higher efficient rendering.
So it's perhaps also interesting for large servers.

A statistic would be nice how much more traffic it would be.
