Boonie, what about the displacement in the cube/jerry? When you pull of a glass you'll be drawing oxygen into the cube. I cant imagine the beer staying fresh any longer than a day, maybe a few days at most.
chris., you know the technical stuff....
I have heard some people have put a soda stream bottle to the top and gassing it back up that way.....
Or, please shoot me down in flames if this sounds silly or near impossible

.....
I was thinking along the lines of a syringe with the rubber stopper/seal inside. Someone would have to invent it, but have a circular keg with a round syringe style "Force feeder" IE when you pour the beer, you could force the rubber/lever down to keep the oxygen out and maintain a small cavity between the beer.
So basically, brew beer, rack beer into keg with 180g of dex or lower and when pouring beer, when it stops to a trickle, push the "Syringe" down.
Probs I forsee, lubrication of the rubber (Dries out) and geting the beer into the fermenter (you could put a one way valve on top of syringe) and lift syringe as beer goes in.
I may be talking out of my arse, or it could be the beer talking.
Thoughts?
