Jez, Yes this is a limitation of the shapefile format (and most drivers, PostgreSQL databases being one of the exceptions).
Try adding -fieldTypeToString IntegerList,RealList,StringList to your ogr2ogr command line. This will transform any field of those types into a String field by concatenating the values into a single string (what you can see with ogrinfo). Beware that if the list if longer more than a few items, there will be a truncation at 80 characters. I'm considering to see if it's practical or not to add an option to ogr2ogr to split fields of type *List into several fields of simple type. Best regards, Even PS: For the record, in http://download.osgeo.org/gdal/daily/, you can find daily snapshots of the source code of the trunk (1.8.0dev) and the 1.7 stable branch.
