Think of the day when USENET dies because ISPS block all access due to the fact someone MIGHT send a copyrighted file. Imagine FTP being mostly blocked and all ports being blocked EXCEPT for certain ones being open for select applications.

If you think Telco and Cable ISP's care about your "Rights" if it costs them money (or criminal time) think again, they'll cut you out/off/down in a second. This is why Safe Harbor must be protected vigilantly.
