Interesting. Other issues that will come to play with an ABM of the intended scales you describe are synchronization of the various asynchronous distributed components, message passing latency, and message passing bandwidth. Hopefully a course-grained sync & message passing design can be developed, because http is not good for either latency or bandwidth (using Myrinet or Infiniband for comparison).
