I'm developing a product for offline use in Brazil in rural areas where there is no Internet connection. I'm searching for a free imagery source which can be used offline in a commercial product.
ESRI and mapQuestOpen are free but their agreements only allow online use.
Is there any free or open offline satellite/aerial imagery for commercial use?

The best option for a world map free software for me was NASA blue marble. http://visibleearth.nasa.gov/view_cat.php?categoryID=1484.
