SRTM is the satellite data that all terrain data is taken from. If you use Terrain data, you are using SRTM data, or derived, which obviously has the same license. DTED is a common format derived from SRTM data.

It certainly makes it look nicer - shading of hills etc for terrain, but technically we could work a way around it.

Technically, given enough time, fake random terrain data could be generated.

No, like most geo spacial data, the governments that release it tend to have their own license. 

By comparison, what other data is provided as examples on the DVD?
