+### v2
+Parallel processes: collectors, cacher and reporters; passing messages over pipes
+(Bash and AWK).
 
-Any errors encountered by any sensor are propagated as alerts by the
-controller, which are in turn actualized as desktop notifications by the
-actuator:

+### v3
+Clean-up, polish and further development of main ideas learned in v2.
