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 :).
