VPN + Remote Desktop (if you're a windows shop) is the easiest way to work from home. I'm in IT also, and often work at home, though I'm required to be in the office during normal hours.
Anyway, Remote Desktop, for those of you who haven't used it, blows GoToMyPC or PC Anywhere and the like away. Your windows PC doesn't simply take snapshots of your desktop several times a second with RD; rather, it just talks with the video, sound and other parts of the computer and then displays that on your PC remotely. THe speed difference is fantastic. Remote desktop is king.
