It seems like POS is all the rage now.  I'm interested to see how all of this plays out in the long term.  The ability to throttle inflation, deflation, and consolidation is an ongoing challenge that can destroy a system if it gets out of whack.  POS looks to make positive movements with mitigating some of these issues, but only time will tell.  As we know from all of history, if the system can be games, it will be.
