Hi,

You can use the tc program, and htb qdiscs to ensure that people are 
guaranteed some bandwidth, so that one host cannot dominate the 
network.As it is the Internet link that is the weak point, you need to 
shape at the gateway.

I am currently working on a script that deals out the bandwidth evenly 
amongst hosts, so that when only one host uses the link, it gets full 
speed, but if two are on it is 50/50, and so on. I hope to have it 
finished in a month or so. Maybe you can use that

Also, if it is p2p traffic you are worried about, you could try the 
p2pshaper. I posted a link in a earlier post.

cheers
