I haven't seen much information on the Internet about the current status of the Jutice Department's Integrated Wireless Network (IWN). The last update on the IWN web site was from over a year ago when the primary contract was awarded to General Dynamics:

I also found this document regarding the FY 2008 budget of the IWN:

The above document does show references to a timetable of modules to be completed. Most of these are in Oregon and Washington State, but some refer to the Gulf Coast. Keep an ear open for developments in that area.
And finally, I came across this site:

The person who launched this site seems a bit mis-informed and paranoid.
