I'd like to take part in, or host an event where I collaboratively code something with a small group of people in geographically dispersed locations.
Is there a web app like jsbin.com or jsFiddle that allows near-real-time editing and code sharing? I'm thinking of the sort of editing you see in Google docs spreadsheets, where the cursors and editing of other people editing the spreadsheet are shown to the other editors/viewers in near-real-time.
