Mixed Ink...

Mixed ink is a tool that takes the idea of collaborative writing to the next level.  I have not had an opportunity to work on a collective document using this tool yet... however the concepts are very impressive.  This is like Google documents with tools that allow you to easilly mix and match content and vote on the "best" version of a document.  Very impressive.
