A real collaboration does not start and end with the soft copy presentations. To have a result oriented meeting one needs to call-in notes, drawings, 3D objects, and the explanations on the white board. These are powerful tools to drive home a point, to get a real feel of the subject in hand, or to invite creative suggestions. Without the power to share these important formats in a collaboration, is a sure recipe for inconclusions. Never miss again on these important instruments, share any of these formats to anyone in the planet.
Video conferencing is not a surrogate option for your local presentation, where you are restricted in explaining the finer points on the writing board as you do in local meetings.
Share your whiteboard across the globe, and the other side sees exactly as you do, with actual writing movements.
