OK, I've seen these before...there's one in one of the Austin Picnic photos in the other thread. It's a tap faucet connected right on a corny keg ball lock coupler. I'm interested in this because I'm going to be kegging soon. I don't have a kegerator, because I'm not sure which direction to go on that yet. For now I'll keep my kegs in a dedicated refrigerator, but you'll just open the door to dispense. (This is a really nice full size fridge in my basement bar. No way I'd EVER get spousal approval to drill holes in that thing. )
I'm curious how these things work, because I'd like the idea of opening the fridge door and pulling a tap connected to the keg, rather than monkeying with a picnic tap connected to 6 feet of tubing. But when I read about "balancing" a tap system the general consensus seems to be that to dispense at say, 12 lbs of pressure without foaming, you generally need about 6 feet of beer line. So if a tap was connected directly to the post with no beer line at all, would that be a balancing nightmare?
