Ok, I missed the meaning of "mix". Thus our advice for Oliver about the cable
network is not to mix the private data with OSM data inside his own copy of OSM
database. It will be OK to render OSM basemap tiles and use for example a
separate WFS-T service [1] for showing and editing the cable network vectors.
Users must just take care that they do not edit cable lines according to what
they see on the OSM map, otherwise all of the cable network data will be
considered to be derived from OSM data and thus fall under odbl.
