"Telecommuting" in academia In business (e.g. IT industry) remote work (aka "telecommuting") can be relatively common (see e.g. a recent StackOverflow blog post). It is exceedingly rare (or even nonexistent) in academia, even though most part of academic work consists basically of thinking and writing, which can be done in any environment. Are you aware of any successful implementations of "remote work" in academia?

Of course, there are many factors making it less feasible - an academic employee usually has other duties (e.g. teaching) which can't be done remotely, there is also the social aspect of research, meetings etc. (although this is not that much different from similar aspects in a programming job, unless we argue that doing science is "more creative" than mere programming and thus requires more physical presence). Also, currently available tools still make e.g. making a web seminar or math meeting difficult (no blackboard), although this too is changing (see e.g. G+ Hangout seminars: TCS+). However, given the scarcity of jobs, "N-body problems" etc., it seems to me that the potential for remote work (even part-time) is, as of now, underutilized in academia.
Doing it part-time is rather common at least in places i have worked. At moment me and most of my colleagues work from home two days of the week (usually Mondays and Fridays for most and Thursdays and Fridays for some) on the days that no teaching is involved. If there is an important meeting we will show up otherwise we skype. I think i generally work on average 6.5 days in a 22 day work month from home.
