This Weeks Challenge
Is It Possible To Disable One Program When Another Is Used ?.

I was trying to think how to disable 'Facebook' when 'Skype' is being used .
After waiting all week to see and speak to our daughter at uni all she seems to be doing when we Skype her is talking to her mates on Facebook.
So if I could accidentally place some software in her new Xmas present of a new laptop running PCLinuxOS KDE to stop Facebook when she is talking to us on Skype that will be good

.
One idea is I know you can stop Facebook (or any other website

) by using
www.facebook.com = 127.0.0.1 in 'Host Definitions' but I need someone to write a script to get this to work.
It needs to disable Facebook when she uses Skype then after she has finished with Skype enable Facebook again.
Any idea's please.
