A friend of mine has just got a new broadband plan... but seeing as it was the only broadband option available it comes with huge overage charges. In fact $1.10/MB! (I was shocked too!)

Anyway.. seeing as this is the case I was wanting to put on some piece of software that can limit the amount of data she can use in a month to ensure that she doesnt go over the limit. I was hoping for a piece of software that I could simply set a data limit for between the billing period (its a month if that helps) and it simply resets at the beginning of the next month. It would be preferable if it gave you some kind of notification of when you had used your data (whether that be a notice from the task tray or a message when you open the internet application) but it is not necessary. If it also warned when you were approaching your linit it would also be handy but is not necessrey again. Being able to check the data throughput total for the month would also be convienent. The programme needs to include data for ALL downloads/uploads that go through the computer (e.g updates, email)... so in other words the total usage.

Any ideas would be greatly appreciated.
