Unveils the mysteries of a sanke keg...
It's an idea, but that would still be a pain in the arse to clean! I like being able to shove my arm down in there and really clean my kegs out!
That would make sense for doing pny kegs though, and you could share your keg brew among non Homebrewers with sanke kegerators without hassle.
Actually I would love to do that at least for one pony. Friends of ours hold shoe tournaments once a week. He keeps a pony in is garage for the gang.
