Someone on some other forums said he was going to release one yesterday for free through the store but I have yet to see it. The other sellers sell limited licenses.
Unless this is a packet spoofer (aka true hack) then it must be dependent on ping. As the house goes to the first person's packet that the server receives.
I can't give you too much info but it's tested and working.
When it's released I'll be willing to give Out a free copy inc source code for review.
It will be expensive but the copies will be limited (max ~5-10).
