This is absolutely an issue with Xbox Live/Sony PSN or RBLs used by
mail servers for reputation purposes. For better or worse these
systems equate one IPv4 address == one user (and possibly one IPv6
/64 == one user). My opinion is that this may be a reasonable or
"good enough" assumption<br class=""></div></blockquote><div class=""><br class=""></div><div class="">Talk to someone who has been sued for downloading or sharing movies.
