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 :).
