I think an inventive trick would be to use cron to every 5 minutes check an IPFW counter you setup to watch his machine's bandwidth usage. Reset the counter every 5 minutes, and if it's non-zero (or maybe above several KB) then "charge" him for the time. You could store this in a simple data file and when the time limit is exceeded then simply set a rule to completely block, at midnight just run a script to remove the initial rule and reset the accounting file. > ps I'm going to encourage him to circumvent any system I put in > place.
