Private IP Filtering
 

Further to the suggestion by dis-k about detecting the actual IP of machines behind a firewall, methinks it would be most handy to have Gnotella filter out any search results that are from private IP addresses, such as 192.168.xxx.xxx
Otherwise, great work ;-)

Hopefully by the next release there will be an option to ban specified IP masks, in which you could just enter, "192.*.*.*" or "10.*.*.*"
