Well that is my point and certainly how I thought the 301 would act. The links only point to the www version of the domain - the non-www has a completely seperate link profile and they are effectively treated as different domains (or subdomains). By switching off the www version the links would point to a dead end, they wouldn't transfer to the non-www version. The logistical challenge here is redirecting the users appropriately if they visit the www version without the search engines passing on the link value from www to non-www.
