Interesting! So, has it ever happened to you to hire a remote worker with a proven track record (say, 3-5 years, references checked) and then realize after some time that this person "doesn't fit the bill" for working remotely for you?

(If it has happened, I'd be interested to know details -- was it because of the specifics of your company's procedures, or something else?)
