Cache coherency, clustering, and Kernel virtualization

    You will be able to cluster the real kernels, yes.  The limitation is
    that it is likely that any given kernel (real or virtual) will only 
    be able to join a single named cluster.
Which is to be expected ofcourse, when clustering the real kernel. I 
assume this would also bypass some of the code that is necessary for 
multi-grid clustering? And that a real-kernel-cluster could act as a MPP 
host for multi-grid clustering over the internet, as you plan? In that 
case, I see no problems :).
