BIND opendns forwarding service

Hi, my project is for people who know BIND, Linux and openDNS. The goal is to forward opendns service. Infact when you use opendns services as DNS for you personal computer, you got filtered results. I want the same result except that you will not specify thses openDns Ips, but my dedicated server DNS. This server will then forward results from openDNS: so it's a kind of DNS relay: normal DNS: MyPc (set with openDNS)<------->openDns server <-------> final website what I want: MyPc (set with my server DNS)<------>My dedicated server (BIND)<--------->openDns server <-------> final website you will get full root access to server. To summerize: I want to use the openDNS DNS filtering services but I don not want the final client to specify openDNS in his network connection, but my own Dns. A kind of gateway between openDNS and BIND DNS server of my dedicated server. Regards
