For one thing it stops MITM attacks. Most people are naive and if they're on an untrusted network and someone MITM'ed their bank connection, they will click through the browser "don't trust this website" warning and bam - they've lost their bank creds. Forcing users through openvpn puts them on a trusted network where such skulduggery doesn't happen (and you could have AV proxies and other such stuff) ...of course, if the untrusted network is truly 0wneD, it could break openvpn, leading to the annoyed user disabling openvpn in order to get a working Internet connection and - well - see the first sentence ;-) You can try to engineer yourself a foolproof system, but the Universe can always engineer a better fool -- Cheers Jason Haar Information Security Manager, Trimble Navigation Ltd.
