Question : DSL Data Usage Meter for individuals in a flat

I am currently flatting and have a shared DSL connection with a low 20GB data cap. This is shared with 3 other flat mates and we go over our data limit which incurs a large cost every 2nd or so month.

I know I do not download much so I would like to show my flat mates a download meter for my computer showing I have only downloaded x amount of data over the last month. That way I am not forced to pay for some one else's data usage.

What free solutions are out there?
