1. Should XMI be installed after GRASS4.1.3 or does the XMI installation
process install GRASS4.3.1 also?
XMI should be installed after GRASS4.1.3 and in the same directory as GRASS4.1.

2. Does it work with Grass4.1.0? and Grass4.2?
Yes
3. Does XMI include a "decent" RGB display? ( with something
more than 250 colors...)
XMI uses existing XDRIVER provided by GRASS4.x installation.
