from the doc: 'NetDown is a Client / Remote secure solution for networks that allows the NetDown Remote to either shutdown, launch applications or URLs on up to 10,000 client computers at the same time. NetDown allows for password protection and encrypts all data between connections. NetDown could be very useful on any network but may really help at schools where you have to launch a program like a word processor or URL on all computers for students to use. At the end of the day you can shut all of the computers off.'
