NMCI is a landbased WAN. It started in HI and Washington, and has spread like a virus to BUPERS, DC, and San Diego. The intent is that everyone gets a navy.mil email address, and they log into a networkcentric environment. So if you're stationed in CA, you can go to WA and log in and still get your email, files, etc. The problem is that they bought cheap computers (Dell Celerons), and the even the simple process of logging on is sooooo slow. There's a bunch of other features of the network, which means there's plenty of other pains in the ass.
A good friend of mine I went to HS and college w/ worked on NMCI when they were building it. Anytime I talk to him, I make sure to tell him my personal thoughts on his work.
