One advantage of using the same screen for work and home use is that it gave me justification for splurging on a 30" main monitor last year. A KVM switches the screen, keyboard and mouse over to my docking station for when I'm working.
I love my usb kvm though I don't put video through it, I switch the display between the hdmi & dvi inputs (toying with the idea of adding audio to it, so I can use my one good set of headphones on both rigs). Multiple displays give me whiplash.

Man, you guys need to move countries a couple of times. That soon sorts out how much stuff you have lieing around. Most of what I own would fit into a few boxes*.
