We could extract all the interesting nodes that already exist in the Open Street Map planet database (http://wiki.openstreetmap.org/wiki/Planet.osm)​. For example pull all the hospitals, police stations, restaurants and ATM nodes from the area defined and format them into basic directory pages on LocalWiki.

This raises the possibility of also doing the reverse. That is: taking "nodes" from LocalWiki and automatically adding them to OSM.
