What exactly do you want to do, hide your traffic from your ISP?
If that is the case, I wouldn't recommend it. It violates the T.O.S. of most major ISP's and they can shut you off if they even suspect anything fishy. You have to remember that if you do anything illegal, not saying you will, but if you did, they are held accountable. Especially with all the P2P stuff these days, ISP's are generally aggressive in regards to covering their own a$$es
