the copyright crap is just an excuse - the entertainment industry wants to control what you do with "their" content.
anytime someone comes up with an innovative idea for using content, they swoop in and sue - apparently they are either too stupid to innovate themselves or it's just easier to sue the issue out of existence.
You got that right.. An idea for Cablevision.. set up a self service storage unit, like you'd put that old couch in and charge $9.95/mo.... company will co-locate "your" DVR and rent that space and grant you access for $9.95/mo ??
