Yes.

Also a quick look at osx server and I see they are using vpnd but we  
may still be able to discover something there.

BTW, you want openvpn because with vpnd you cannot connect to some  
other vpn device?
That is my reason. vpnd does not appear to support as many remote  
configurations. I needed ipsec and it didn't look promising with vpnd.
