>I think whiteboards are the most important tool for network design (...)I can’t even tell you the number of disasters averted by 2-3 great network engineers arguing over a whiteboard.

I strongly agree with this statement and think it holds true for a lot of IT/dev/ops fields.

That's something I miss when working remotely. Has anyone found a tool that is seamless enough to allow for true interactivity, as much as be in the same room and sharing a whiteboard?
