I once made a device that does something similar to a beer engine. I bought a short length of small, threaded copper pipe, a copper cap to screw on one end and a hose barb to screw onto the other end. I drilled six or so tiny little holes into the end of the cap, attached the other end to a hose from a picnic tap of kegged beer. The beer is forced through the small holes and breaks the gas out of solution. I found it in a Zymurgy gadget issue many years ago. It makes the beer really creamy. When I get home I'll see if I can add a photo.
By the way, Phil, we told you so!
