Found this 
article on BBC News.  Do you think your commute to work is far?  Well, consider working in city A (London) and living in city B (Barcelona, i.e. "fill in inexpensive cost of living city").  WOW...Talk about the jetsetting lifestyle. hehe... The article points out that due to high cost of living in major business cities (i.e. London), the emergence of mobile computers, broadband, cheaper airfares and importance of quality of life, some people are living in internationally affordable cities and commuting to work via airplanes.  There are several comments to the article by readers that actually are doing it.  How cool is that?   
"If you book in advance you can get one-way flights from London to Barcelona for £15.99 plus charges. The standard day single by train from Basingstoke to London Waterloo is £15.40."
 My master plan is; post MBA work in Europe for a couple of years (consulting) and afterwards head back to Cali, most likely San Francisco.  I have traveled to many international cities [Amsterdam, Barcelona, Budapest, Hanoi, Krakow, Madrid, Munich, Mexico City (DF) Prague, Paris, Saigon, Tokyo, Yokohama, Vancouver, etc], and SF (in my humble opinion) ranks up there amoung the many great international cities.  It has culture, ethnic diversity, nice people, conductive for active life styles (i.e. surf, snowboarding).  I've had another master plan once but that didn't work out and I'm better for it.  But I digress.
In addition to being able to work in Europe, how fabulous would it be to say in a conversation, "Oh me?  I work in London but I live in (insert affordable city)."  Very cool.  hehe...
