The gvSIG sample project uses uDig and OpenJUMP sample data :-)

With more time I would like to add also PostGIS and any OGC service is
running on the LiveDVD... but first I have to got gvSIG installed!

Note that the Cartography Institute of Catalonia will free a sample
dataset, it would be great to have it at the LiveDVD if it's not too
much disk space. Anyway, we don't know when it will be ready so I
wouldn't count with it for this version.
