Exactly. I think it is a matter of persistence granularity. The 
quantum size of an event(s) that need to be replayed (have life in 
another timeframe, or be user rather than time driven). Disk save 
snapshots can sometimes be far too chunky. Unless they somehow 
encapsulate fine grained history too.
