I tried to write a Stellar document that summarizes different views on 'orchestration'. As you guess, this is hardly possible. To accommodate all viewpoints, I should write such an ecumenical paper that it would be boring to read. We decided to proceed differently. I wrote a position paper, that reflects my viewpoint (shared by a few :-), and invited colleagues to write a 'response to'.  The compilation of the paper and the responses will provide a nice overview. It will be discussed in CSCL 2011 (HKH, July 4). If you would like to join the discussion, you may send me a 2-3 pages responses by June 10th.

The paper is at http://www.teleurope.eu/pg/file/read/93714/whitepaper-on-orchestration
