My in laws own a small business. Their employees are abusing their internet access spending lots of time on sites like Ebay and Craigslist. They asked my opinion on a solution. I've looked a Net Nanny, and think it might work. However I thought I would ask people here their opinion. I know a gateway firewall like Smooth Wall would work, but I'm hoping for something client side that is VERY simple for them to administer themselves, since I live 700 miles away.
