Last year the Colorado Dept. of Revenue estimated that it'd cost $9,820 
to make the change; this includes the cost of updating about 300 servers 
running Microsoft Windows, GNU/Linux, other Unix, and HP-UX.  See:


My guess is that the actual cost of upgrading has been underestimated, 
as the state has a lot more than 300 servers.  It's just that only the 
Dept. of Revenue bothered to estimate the cost. There's also the cost to 
private citizens both within and outside of Colorado, but presumably the 
Colorado legislature doesn't care as much about that.
