We've just got a 20 GB broadband plan, and I'm wondering about how this is going to work out - what's to stop someone from downloading several movies in the first week, then everyone getting bitchy when everything reduces to something like dialup speeds, which is almost unusable if everyone's trying to use it?

I've had a bit of a look at the router's control webpage thing, and it doesn't look like it's capable of much of this sort of thing.  It's a recent DLink wireless router of some kind (I think I bought it last year) I can't tell you exactly at the moment as I'm not at home.  There is a separate ADSL modem.

This needn't be linux-based, if there's an off-the-shelf appliance of some kind I can buy, that would be great - I suppose this makes my post slightly off-topic, but I'm hoping I'll be forgiven.  I don't really want to spend very much on it, though, $300 would be an upper limit.  I was thinking perhaps something like this would come in handy:

I'm imagining this won't necessarily be possible - won't the router act as a switch, and only be sending my computer packets its interested in? And if it is possible, then what will be the impact on network performance?  And what software do I use? I don't need anything too fancy, just an ongoing sum of useage per MAC address or something like that.
