...what happens to all of the offices? What happens to people (like me) that would face a hostile WFH environment?

"Instant Messaging (IM) with presence is no longer a thats nice technology - it has become essential to break the email avalanche and to provide the familiar interface that our younger teleworkers demand."

'Demand'? I had a good laugh at the last young worker that 'demanded' anything from my infrastructure. We're adapting, in alignment with budget and workflow demands, but it won't be immediate. I'm also wondering at your thought process for this quote. We're already starting to see increased cases of burnout and less leisure time arising from constantly being in touch with SmartPhones (and probably using Email). How is using IM to decrease the 'Email Avalanche' going to do anything but EXACERBATE the problem by causing an 'IM Tsunami'?!? The expectations on the other end are going to RISE (IMs are supposed to be answered immediately, aren't they? Hence the 'Instant') not fall, since an Email reply can be immediate, or take half a day.

What will happen to our leisure time when 'WFH' becomes this standard? The lines have already been blurred...
