Hi Steven, interesting, my experience with Qt is very limited, but it definitely is something to keep in mind - as are your other experiences.
Note, when I wrote "minimal distribution" I was thinking more along the lines of minimzing the amount of work to build the distribution. Besides drivers and languages one could also provide subpackages and other installation options. We have to be careful there too :).
