There are some funny special cases that need to be considered. How
does your proposal handling failing components in the cluster? Imagine
a network failure that split your cluster in two parts, each fully
functional but unconnected to the rest. The so called split-brain
syndrome. Now each cluster half will continue processing and assumes
it is authoritive? Imagine a database system being split up into
two systems ...

(Even funnier - there is a currently under development supercomputer
architecture with exactly that kind problems but in one single machine.)
