From a post today from wilderssecurity forums regarding KSO,
"We are currently giving away 300 full working serial numbers for KSO07 for those of you who simply cannot wait. These will be provided on a first come, first served basis. Please contact David at email@example.com to obtain yours whilst they last."
I have no idea whether or not all 300 licenses have been given out yet. I just requested one just in case they are still available.
