This is already happening for SV startups founded by foreigners/1st gen. It's much cheaper to keep engineering in India or E.Europe, save about 50-75%. I worked at Prezi, founded by Hungarians, and 2/3 of the company is in Budapest, with a smaller office with mngmnt/marketing/finance in SF. I believe GoodData (founder is from Czech Rep. I believe) is doing something similar.
