I'm confused by your requirements.  You say you want all the computers 
to have the same data, and then in the next breath you want to be sure 
that they don't have the same data when one of them is "compromised."

I think your problem here has nothing to do with the data duplication 
(which arch _may_ be able to help with, but it seems doubtful it's ideal 
for your application), but in defining when the data is "compromised."

What do you mean by that?
