Org mode works on text files that are formatted in a specific way, the basic syntax is not more or less complicated than Markdown, so you can in principle use it from any editor you want. The way I usually collaborate on things like papers / technical documentation is to assign specific sections, parts of the exposition to different people. I think it is rarely productive to edit the same part of the document at the same time, but I might be wrong or simply haven't found a use case. Admittedly so far I have used Latex for serious projects, there you simply create a master skeleton file and then people work on different sections individually. The choice of editor then doesn't matter. Something similar could be done with org mode. I've only used org mode only for personal note taking, todo lists and drafting documentation, but I would imagine it would scale fairly well to small teams using it.
