doing SEO from distant locations..

[NewKidOnTheBlock]

Is this (easily) doable for an SEO:

Earning the income of an industrialized/high cost of living country, but living in a low cost of living country (Thailand, certain places in south america,...)?

or is accountability too big for most clients/companies/agencies?

(actually, I'm mostly wondering if this is doable for half the year, as I'd love to escape the winter in Germany regularly and see friends having a great time in such (sunny) places, at the moment ...they work on an oil drilling platform on and off, though - but Id prefer SEO;-))
