A slight correction. DOWNLOADING is legal in Canada for Personal Use - We pay a tariff on recordable media already.
The judge ruled that by not advertising, not profitting, (i.e. not making a POSITIVE act) the mere placing of files in a shared folder is akin to having the photocopier in a library.
The Supreme Court Of Canada recently (2004) that the photocopier issue is NOT infringement.
Therefore, in CANADA only, and until Parliament ratifies WIPO (God, I hope they don't), sharing files is NOT infringement provided there are no POSITIVE acts to make it one, and DOWNLOADING is NOT INFRINGEMENT if only for PERSONAL USE.
