The argument regarding taste is irrelevant. Shipping and packaging costs is where the discussion should lie. However, the overarching issue is how perception interferes with the drinking of the beer.
Oxygen Transfer: Beer is carbonated, so the positive pressure is going to cause any leakage from a bottle cap to be outwards and not inwards. If you have oxygen going into either a can or a bottle, the seal is bad and the least of your worries is oxygen transfer.
Light Transfer: As for light transfer, cans are superior. However, as long as you're not storing your beer bottles in a window, the effects are going to be little to none. Keep your beer in a cabinet/refrigerator.
Imparting flavors into beer: The soda industry has already solved this. Drink cans are all plastic lined, so that's not a problem (The plastics have been designed to minimize the change on flavor). Glass isn't transferring taste either.
Packaging: The capitol costs of canning are higher than bottling. However, in the long term the cans will cost less per unit than bottles.
Shipping: Bottles are very inefficient. Looking at a pallet of bottles, the necks cause a large amount of void space. In addition, bottles are also much heavier, further increasing costs.
edit: Also, if you perform difference tests, a triangle test should be used.
