Dallas,
That is very cool and makes tons of sense in this day and age!!
My sister's husband does the telecommute thing from Florida, he has a seperate office at home with seperate network, phones, fax etc. nothing like this guy but a nice setup and it beats the travel.
If you are going to do it from home - you NEED the seperate space, not the corner of the kitchen table
My work office is not as good as this one but I now have 3 19in monitors on my Dell 745, left monitor has "Start" and icons and this is where things "pop up", middle monitor is where I work, and right monotor has video feed for the main door and the print que for the "lab" printer - NO 35 page print jobs

To the left of all this is another 17 inch monitor with a video feed for the main computer lab area on another computer. I have 2 other work areas in my office with 3 more 17 inch monitors, both areas are for testing and repairing things.
I wish I had that guy's setup at home

but not the electric bill :-(
