> 1) Duplicate IP checking (ability to limit connections by IP)   
      
   If you want to limit connections (block extra connections from same IP), you   
   can configure your firewall to do that. At least Shorewall can do that.   
      
   If you want to kick out older connections, then some bz-scripting could handle   
   that. This works only for telnet connections.
