DSLAM problems, and online music retailer "sharing (Score 2, Interesting)

Two items of interest: 1) This summer, through a fluke, I found that at least 3 unique IPS can run over TELUS' ADSL service. Technically, the DSLAMs are supposed to only allocate 2 IPs. This potentially destroys any basis for TELUS to claim unique identification of users by IP address. 2) It is possible, by looking at the HTML code for a Canadian online music retailer, to figure out how to get their entire music library to stream in high quality wma. The retailer appeared unconcerned when notified of this and deemed its exploit unlikely. Nonetheless, they've essentially made the copyrighted material "freely" and knowingly available on the web. Does anyone have feedback or thoughts on whether their actions constitute illegal file sharing per Canadian law?
