If the beer is carbed with beer gas, probably not much. The widget works on high pressure and low carbonation (achieved by adding a minute amount of liquid nitrogen to the bottle before capping). Low pressure/low carbonation probably won't yield much of a spectacular result. On the contrary, if you overcarbonate to achieve the high pressure requirement, you'll just get foam.
I read on another green forum about some guys who tried to replicate the liquid nitrogen bottling process and had mixed results. They couldn't regulate the amount well enough to guarantee success and gave up on the idea.
