[GRASS5] NVIZ license problem

[Bernhard Reiter]

The license of NVIZ does not seem to be free software.
From: 	src.contrib/GMSL/NVIZ2.2/LICENCE.txt

The last sentence renders it incompatible with free software (and with
GRASS therefor.) :(

We need to contact the authors and politely ask them to make it free
software compatible with the GPL. 

Is anybody still in contact with them?
