SyncSpace for Android provides a zoomable drawing space that can be shared in real time over the net, a sort of shared whiteboard. Turn on synchronization and send a link to the document to others who will be able to see your drawing and also make changes using SyncSpace. The resulting drawings can be emailed as images, edited offline or saved for later editing.
It's the perfect whiteboard replacement for distributed teams. See a demonstration video at our web site, infinitekind.com.
