For a little over five years, I worked as a computer consultant. This job required me to travel away from the house on a regular basis (spending anywhere from 100-200 nights a year in hotels). Being married, I got used to staying in regular touch with my wife via instant messenger. Then, when on an extended trip to Europe, I added video chat to the "keeping in touch" toolset.
I'm no longer a road warrior. In fact, I frequently telecommute. Still, a lot of the daily communications happen via IM and sometimes even video-chat. While our house is by no means large (only 1400SqFt.), my work space and my wife's work spaces are in different areas of the house. Using computer-based communication tools is often the most efficacious method for communicating. I can't decide whether video-chatting is better or worse than IMing someone in the same house. Still, either is preferable to screaming.
