Hmm, are you talking about HPC clusters or other large machines here? I'm 
not familiar with this, so a few references to existing designs would be 
appreciated.

Apart from my comment below, it sounds like a really interesting project. 
Is this a research-project or something commercial?

Uhm, ok. I think this is _way_ outside the scope of Kernelnewbies, and it 
is definitely not a newbie project.

If you are really serious about this, I'd start with listing all the 
different elements you need to share and then an initial idea as to how to 
share those between individual systems. I have an inkling that you'll find 
out quite fast as to why the current kernel does not support this out of 
the box.
