Hi Flying Chinaman
Please note that I do not represent or have a vested interest in any of these services – I have been a user only and found them useful.
Google will help you locate their websites.
All you need to do is sign up online. You will be asked to download some software and a username/password.
You can use http://www.whatismyip.com before and after logging in to see which server in which country you are connected to.
Please note that these services reside ABOVE your internet connection. ie you MUST have a internet connection before you can access these services.
I cannot say whether it can be used in all/most countries – I suppose it depends whether the local ISP blocks these servers or not. But I have successfully used it in Malaysia, Singapore and Indonesia and connected via US, UK and Dutch based servers.
From my experience, Kryptnet is the better of the two but more expensive.
