Testing OpenVPN?

Hi all!

Has anyone succeeded in replacing the official IPsec feature (based on 
racoon) with the unofficial OpenVPN port, in gateway-to-gateway VPN 
configuration?

More: is there a way to get a pre-build net4501 image with m0n0-ovpn, 
for testing purpose?

All sort of feedback is welcome.

Thanks in advance.
