   In which sense do they "interoperate"?

   I went to the trouble of setting up a personal OpenVPN server (and   
   corresponding clients) specifically because of the endless problems   
   I had with firewalls when using PPTP (and I don't know about other   
   people, but I can't make any change to most of the firewalls to which   
   I'm exposed; and even when I could I still had problems when several   
   machines within the same NAT subnet tried to use the same VPN).
