[Homeroast] Using CO2 to preserve freshness?

For the record, coffee sealed in an airtight or loosely tight container will 
be much worse at 30+ days than coffee beans left to the open air.  Those 
stored will have rancid smell and nasty taste, where those left to open air 
will be stale and lifeless, but the taste will be tolerable.  Definitely not 
a goal for homeroasters, but interesting on it's own.
