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."
Here's what my parents used for me, back in my BBS days:
"Get off the computer. Now."
If you were on the computer when you weren't supposed to, the phone cord from the computer to the wall would dissappear. Eventually they found the phone cord I bought at the hardware store, then the damn wall jack dissappeared.
