From the face of it, I don't think it'd work in my case. Firefox is always running on my system, so I'm guessing, if I grant X kbps to Firefox that's always going to be reserved for Firefox, even when I'm not using it. Or is a grant only implemented when the application that's been granted the bandwidth demands it? I suppose it depends on how intelligently NetLimiter implements these things. When it comes to bandwidth throttling apps though I have a bad gut feeling that there will be some bandwidth lost from the total when I start capping apps.
