I'm a little confused. I'm outside USA and I want to browse some restricted content for users located outside of the U.S. Can I do this using Sshttle and a VPS?
Yes, but you need a server in the US, so you can ssh to it.
Just so you know, for anything that works over a socks proxy you can already do that easily with ssh (using the -D switch, check the manpage). You then need to configure your client app to use it (e.g. if doing ssh -D locally, in google's chrome, go to tools -> preferences -> under the hood -> proxy settings -> manual, then fill with localhost and the port number)
