Security options...
 

I allready know GP's look at IP addresses when dealing with hackers
but how about the route they commonly take, and mac address checking?? It is becoming easier for people to falsify a MAC address and IP address. You only have to know how.

the graal client could also be given option to connect through a proxy server for some people that are behind such a device. I used to have problems with that, until I could do NAT and PAT with a server I own now.
