Codepad/ideone style collaborative web IDE?

Question

I'm looking for a simple collaborative web-based text-editor which can compile—and show output from—a few popular languages such as: C++, PHP and Python.

Research

Editors

• Ace
• EditArea (people prefer Ace, e.g.: web2py and ideone moved to Ace)

IDE styled editors

• AmyEditor
• Cloud9
• CodeMirror
• Eclipse Orion
• ShiftEdit

IDE styled editors which compile

• CodeRun (supports C#, JavaScript and PHP)
• Programr (supports Java [and Android!], C++, PHP, ASP.NET, C#, VB, Flex, Flash, iOS (UI, ObjetiveC), Processing, JavaScript [incl. JQuery and AJAX], Ruby, Python and even SQL [not sure for which DB].

Pastebins which compile

• codepad
• IDEone (IDEone uses Ace)

Collaborative code editors

• collabedit
• Etherpad

Conclusion

I have been thus far unsuccessful at finding a syntax-highlighting, code revisioning, collaborative editing web-based IDE with a shared compile/interpret debug console.

Can you recommend one, preferably free? If there aren't any; I'll create then open-source a proof-of-concept.

Koding provides an application with Collaboration for teams built in. Ontop of that, the you have full root access to your VM, so it supports any Linux tools that you want to install. Comes with all of the standard languages (Python, GoLang, Node, etc) as well :)
