Hi Woj, To address the second half of our email exchange: I did notice the sentence that addressed Dave's concern. However, my point was that the charter claims that L2CP will have a specific benefit ("avoiding complex cross-organization interactions"), while it is far from clear that in this respect L2CP is any better than other solutions. I believe that the charter should avoid stating benefits that are debatable and therefore suggest that the text that I quoted in my first email be deleted from the charter.
