A couple weeks ago, Magnun and I were trying to implement a new feature for CairoPlot 2.0, which will be called Series. At the time, we decided to create a draft of what we were doing before actually coding and versioning it.
Both of us were stunned to find that an online colaborative programming ide didn’t exist. So we opted for Google Docs which filled the gap but not without some problems (as no syntax highlight).
Today, Magnun just told me about the Mozilla Labs Bespin which aims to be exactly what I said before: an online colaborative programming ide right inside your browser. Check out the project link to see what has already been done.
I do hope these guys keep going with this, the interface looks great and their idea of reinventing the wheel (as they did for the scrollbars and text input areas) is not bad as they do it for great optimization.
