People on cargo ships or oil rigs still usually have regular homes that they live in when they are not working which is often for weeks or months at a time. Google uses it's employees year round.

I wonder if this might be a good solution for the software industry to avoid burnout. Have people live in SV for designated "crunch" periods where you work for 70 hours a week for 2 months, then go home to somewhere cheaper for 2.
