It seems to me that there is at least one striking difference worth naming, between systems which have been designed and understood from the ground up, and evolved systems which we have tweaked and adapted to our purposes. Cars vs. Cows.
While larger systems may contain subsystems of both types, I expect limitations on the granularity of integration, exactly because our limited understanding of evolved systems limits our flexibility in interfacing them with other systems. Maybe all we really want out of cows are certain chemical processes in their stomaches, but cow systems are hard to disentangle, so we'll leave them as units for some time to come.
I recall Drexler having written about this issue regarding nanotech.
