I am very interested in an open source web based ide, I would probably take note from bespin moving from canvas to dom is that reimplementing a whole bunch of stuff from scratch that you get for free with dom is a hard thing

I have looked at cloud9 and its an awesome project, but I feel uncomfortable developing against it because it doesnt feel "open source", can anyone expand on their experiences with it? I sent in one patch was ignored and it seems all / most development is aimed towards their commercial offering.

I would probably feel more comfortable if there was a completely open source community edition which cloud9 was downstream from, somewhat like chromium / chrome
