Hi Brian,
Please also have a look at OpenStreetMap-in-a-Box
(http://dev.ifs.hsr.ch/osminabox). It contains Open Street Map data in a
database structure which can be used for GIS operations with PostGIS. It would
allow to include a local dataset on each DVD without changing data structure
each time. I support to include the Natural Earth dataset. But I'm not a big
fan of special local datasets. We're already struggling with the Spanish
dataset for the WMS shootout
(http://wiki.osgeo.org/wiki/Benchmarking_2010#Datasets).
Regards
Pirmin
