Big communications demands to keep them synchronized. You would need to 
ensure that the copes all got the same sensory inputs. There are about 
10^11 spikes per second in a human brain that need to be at least hashed 
and compared to detect tampering, and the maximum lag cannot be too 
large or there will be a window to do nasty stuff in.

Of course, the copies might simply do a high level scan that the others 
are "pure" and keep the agreed on core values. A bit like the analysis 
of copyclades Carl Shulman did.
