In this section, we articulate the roadblocks that must be addressed to make a market/systems integration suc- cessful. In our opinion, these challenges are not in the market details. Rather, we think that the biggest chal- lenges to their adoption in systems will come fromunder- standing, supporting, and using these mechanisms. After presenting each challenge, we consider action items for the general systems community, as well as for systems market designers where appropriate. In our view, a mar- kets/systems integration could fail if these challenges are not overcome: Allocation Policy Must be Explicit. One of the un- comfortable realities of a market is that it forces user communities to confront their social allocation.
