rdave12: I had a look through the Vista parental control, unfortunately the minimum 'allow' time is 1 hour, whereas the littlen' is restricted to a max of 30 mins per day, so need something more flexible.
MAJ: My modem / router is old. Very old! It lacks any capability to do anything but be a modem and router!
MAT ALAN: The most viable suggestion so far, but am not so keen on the USB memory stick. It's too likely to go missing in this house!
Please keep suggestions coming.
