Look. It is RAW >>> VPN >>> TOR not RAW >> TOR >>> VPN.
Please do not forget that. I am 99% sure there is no reason to boot tor without going through a VPN. Now you can do VPN >>> TOR >>> VPN2 >>> CGIPROXY >>> Etc.
But never Let your ISP know you are running TOR that is the primary purpose of a lot of VPN users.
