Re: the volcano disrupting travel and thus promoting virtual working: One of many articles to come in the next few days, I'm certain, this, thanks to Amy Millman, "Stranded Travelers Turn to Teleconferencing," by Kevin O'Brien in the NY Times. My favorite anecdote:
In one case, a couple stranded in Dubai decided to televise their wedding vows over a Skype video conference to guests gathered for their wedding ceremony on Saturday in England, Ms. Milosevich said.
Saves on catering costs, never mind those costly centerpieces.
