Awesome post. And you can kind of do this even working for Megacorps - in fact if you are working for a Megacorp, have a desire to see more of the world, and are _not_ taking full advantage of the ability to internally xfr to another country while remaining in full employment... well you're missing a trick.
And it's never too late - I did the above from Sydney to London at the ripe old age of 33, and have seen tons of Europe and the Nordics over the past few years - with 5 weeks corp leave, 2 weeks public holidays and weekends, you can do lots of travel if you plan it a little. Sure it's not quite the same, but it's a bloody good compromise if you're more tied down / risk averse than an intrepid 21yo ;)
