Just an idea here, would it be at all possible to set the vmu tool up in a way that when you are approaching your monthly 100gb or 30gb peak, you are emailed say when you are within say 5gb's of that limit? I only ask this as i've managed to clock up 99.98gb without realising! I leave my bit torrent client downloading to its own accord on a second machine, with it set to stop downloads during peak times, however i must of been getting some really good speeds recently so i've almost clocked up 100gb this month with 6 full days left till the usage is reset. This now leaves me with a problem, 20mb left for 6 days or i get a warning email.. grr
Also I think that when you have used a lot (say 40 GB +) the scale on the little progress bar looks a bit silly and just looks full up all the time. I know it resizes dynamically depending on your usage, but maybe it should resize in larger intervals?
