I meant that if one user can misconfigure the openvpn setup, he or she
have the same potential to misconfigure the ipsec setup.

I see one difference: AFAIK when you are using ipsec with nat-t, you
have to give up some of the protection that the AH gives to you, and you
stay only with the full ESP protection. With openvpn, you use the
tls-auth directive and have the same level of protection that AH
provides you. Implementing and keeping IPSEC solution is far more
comples than a openvpn solution, so i would definately try the openvpn
solution.
