I'd be interested in this information as well- I'm in the process of trying to move 1200 miles south to Central Florida where my brother lives and a remote work job would be immensely beneficial! But I do worry about some of the cons (and I'm sure there are some, otherwise most IT pros would probably be doing it).
Certainly social interaction is one con, especially for those that are people oriented and less of an introvert.
I have had the opportunity to do it in the past and sporadically where I work. Never 100% full-time though. When doing it you must be able to prove your worth to the company. I have seen people misuse it and ruin it for other people. You need to be good a t communication and be prompt in your responses. Successful telework or WFH (Work from home) requires the ability to be able to reach employees quickly. With Skype, VPN access and reliable internet access, you can pretty much work from anywhere, you just have to be responsive.
