Metered HTTP Proxy?
Jon asks: "My brother-in-law has three teenage daughters. The only thing that he has to hold over their head is being online. I am trying to find him an HTTP proxy server that has metering built in. I started with Squid which has the authentication stuff in it but we would like something where we could allocate minutes, like some of the WiFi stuff you encounter at a hot spot."
Why do you actually "need" this? Would your life be so much worse if you just let them use the Internet however they wanted?
