Very little of our work happens individually. Often, ideas and positions and proposals and followup work happens collaboratively. For example, while I might be submitting a position paper at this dev summit, it is not the case that those ideas are entirely mine. My position has evolved as a result of work I have done and will be doing with others. I think, accordingly, multi-person position papers should not be ruled out in future editions if this format is continued.

This is particularly an issue for any third-party organisations who might be involved - the organisation might have a position they want to submit, but is the only way to do this by just each individual submitting their own, despite their main reason for doing this in the first place that it's for their work/organisation, and the points are largely those of the organisation anyway?
One would think it would make a lot more sense for the organisation (or relevant parts, at any rate) to be encouraged to collaborate internally, submit a group position, and then if accepted, simply send a single representative thereof.
On that note, issues regarding a lack of support for third-party organisation was exactly the position we wanted to submit from ShoutWiki. But, er, this?
