It will not work. Today's average internet user is technically incompetent to set up something complicated as non-standard VPN connection, leave alone third-party one, like OpenVPN. The second problem - is monetization. Most people wouldn't pay. And the last one - you cannot alter an iPhone/iPad and other closed systems. Seems like it is possible to port (recompile) openvpn to android. (IPsec and GRE probably would be discarded on ISPs) btw, openssh's built in socks proxy is a great deal, for linux laptops or netbooks, but you still need a DNS server.
