I have no bike industry knowledge, but assume if a distributor or manufacturer doesn't give you a dealer account that is because of amount of sales, not because of type of business. A " van" or " home" type LBS likely does more repair and tune ups and doesn't sell tons of shoes, gloves, helmets etc.
At my work (not bike industry) I sometimes try to buy direct, and then being told due to low expected sales they want me to go through a dealer instead. They only set up accounts when they expect you buy a lot all the time.
