I want Collaborative Sticky Note software (like [url removed, login to view]). Basically in the home page users should be able to create a new "wall" by entering the walls Title and Subtitle, and one identifier. Once they enter their wall, they can share the URL with other people, and multiple users should be able to create new sticky notes in that wall in real-time (again, please look at [url removed, login to view]). Walls should be automatically saved until erased by their creator. Sticky notes would consist of text, but users may also attach an image or a video (by providing the <embed> code or the URL). Users should be able to attach videos specifically from Youtube AND from Youku.com.
You can also look at http://corkboard.me. It is very similar to what I need.
Finally, users that are looking at a virtual wall should be able to chat through something similar to Facebook's chat. Look again at [url removed, login to view] to get an idea.
