I disagree on one point. I've spent much of my career working with remote offices over the phone and with desktop sharing. I have to say, group video conferences really don't cut it. However, one on one calls and video calls work really well and you can get to know your coworkers. Its so much better to have one on ones with others and not have each other worry about posturing in front of their peers. Group video calls are at least just as useless as group meetings.
