For us the solution was to rent an co-office space in Argentina (a great one btw: urbanstation.co.ar) In Thailand and South Africa this was less of a problem: in those places we had a small spot to work and we often went to internetcaffees in CapeTown, doing the real work at home, disconnected from the web. Which is immediately a good trick: disconnect from the internet and you'll get most of your work done: prepare work, mails etc. Then connect, send everything, get the mails, and disconnect again. GTD and sticking to it is a large part of making this work, otherwise you're or online on Facebook all the time, or working too much :)
