This InfoWorld article describes Steve Cooper's plan for a "network of networks" for homeland security.  The message is similar to the one I blogged last week at NASCIO.  I have a few comments:

• This needs to be built like the interstate highway system: the federal government provides the funding and sets the standards, but the states (and others) build it). 
• We need to step up to the plate and help define this.  If we do, it will likely be useful for much more than homeland security, the same way that the interstate highway system is useful for more than national defense (its original purpose and justification in the '50s).
