This is why I moved our standup to Skype. Even if people are away from their computer, you can join a group chat via Skype mobile from the car (handsfree of course). I agree with some of the other points, but if you start to get a good rhythm on how the meeting is run, overages can be minimized. I couldn't imagine not doing this meeting at least as virtual meeting. The last thing I need is to be archiving E-Mails as PDFs.
