I only ask because this is something I'm very much interested in doing myself, but I'm very apprehensive about making a big change like this due to job/money concerns.
But I'm worried by the first move. Where I live I got a lot of job opportunity but I don't know if I will be able to find a job in another country quickly enough and it doesn't work very well remotely.
If you have a popular web service or a iphone app you could do it.
Since you just got your degree, my honest advice is this: 1) Be slow to accumulate stuff. 2) Exploit the location where there are a lot of jobs, but do it in a way that doesn't tie you down for 4 years. Do consulting or contracting, or become a co-founder of a startup that is a virtual company such that the company isn't tied to this location. You need some good work experience, which you might have gotten while getting your CS degree, but if not, get it, and get some savings to boot. 3) Start practicing it. Start working away for a week at a time.
Unless you're independently wealthy you can't really spend your time without any work, so the challenge is working while you're a nomad.

Like anything else, it is best to work into it a bit at a time. It might be worth trying a 3 month consulting gig and then, after saving that money, try 3 months on the road as a nomad and see if you can earn money consulting that way. This way the initial gig covers the expenses if the nomadic lifestyle turns into a vacation where you just spend money.
But for us, paramount to being able to do this is the ability to earn our expenses. Most startups look at burn rate, we are keeping a keen eye on revenue vs. living expenses.
