I think your best bet is to solve the youtube filter&#x2F;access problem in a different way. If you have a cable modem and&#x2F;or wireless router, it may let you filter web traffic by MAC address (mine does). If your sister uses a different computer than you, you could block access for her MAC, and allow access for yours. If there&#x27;s only a single computer, software that does web filtering with a password-based override would probably work.
