Another point about trying to get government entities to switch to Linux:
A lot of government agencies have strict rules about accessibility for people with all kinds of handicaps. Some of these require voice recognition for operating a computer or other adaptations for people with handicaps.
I know nothing about what's available for Linux, but in reading discussions among people who *do* know about this, it seems Linux isn't there yet. Voice recognition has to be deep and available as a system function. The deficiencies of Linux in this regard have kept some government entities from adopting Linux.
Just so you're prepared in case the topic comes up...
