I highly doubt its a smoker. Where does the fire go? And where are the air holes? And it's stainless steel, which would look awful after a few uses. Smokers are cast iron or enamel plated steel or ceramic.
I want one of those egg shaped ceramic smokers. http://bbqgrillsshop.com/egg_shaped_ceramic_grill
Those things are pimp.
A home made version can be made from a deep ceramic pot with an upside down rounded shallow pot for a lid. I guess you need a base with some holes in the bottom a means to change the size of the opening.
Got a small Webber bbq/smoker from BBQ's Galore. $100. Now I don't use my gas bbq... ever. Taste is 100 x better when using charcoal.
