[Live-demo] What dataset should your application use on the LiveDVD?

As we are running into physical size limits of the LiveDVD, and as we 
wish to provide a level of consistency across applications, the next 
OSGeo Live DVD will include a common dataset which we will encourage all 
applications to make use of.

For this coming release, we will not mandate use of the common dataset, 
but we encourage projects to use it if they can. (We will likely be 
mandating projects to use the common dataset in future releases)

So our next question is "What dataset should we use?".
* The dataset needs to be reasonably timeless - (we don't want to ask 
projects repackage new datasets every year)
* We want to cover a representative set of layers.
* We want the datasets to be able to be made to look "sexy".
* We want to keep the size of the datasets to a minimum.
* The data needs to be available with a suitable open licence.

Unless someone suggests a better source, we will be using the data from: 

Which layers would be suitable for projects?

I suggest:

1:50m Cultural layer
Admin (countries & states) polygons
Populated places - points
21 Meg uncompressed (less if we trim)

1:50m River and Lake Centerlines - lines
~ 400K uncompressed

1:50m Natural Earth 1 with shaded relief and water, raster:
171 Meg uncompressed
