Use Netstat Gui

Greg,
I work with some folks who have developed a free training program for high school students that teaches them how to be safe on the Internet. I have asked TechRepublic for permission to use your posting for the Netstat Gui but have only heard they are researching it.
The program is Hacker Highschool under the auspices of ISECOM. We try to use only freeware/GNU license programs so that the kids can use tools to help them learn without spending any money.

Permission would be great (of course it is also acknowledged).

Thanks
Rob Dodson
