Ads by Google

You can find a lot of multi-user whiteboard collaboration tools online today but most of them offer the same functionality. These types of web apps allow you to easily share your ideas by using drawing tools. CoSketch is a similar tool but it has a couple of nice features that you cannot easily find anywhere else. This collaboration tool allows you to upload images for discussing particular details about the picture, or use Google Maps to give location directions.
