I am a network geek and I initially started to use witopia only for watching US tv shows when out of the country.
After A while I realized how good the service was and I started to use it for just everything, The best money spent on network services after buying my first 300 baud modem. I love the flexibility (many server in a lot of different country and the possibility to use different access options: PPTP, IPSEC and SSL. Support is great and always on-line. It is also possible to configure your own router (this is not supported) or get their own in order to connect your network.
