I believe I read recently that tc (traffic control) and iptables can be
combined to provide a solution for what you're describing. Someone
correct me if I'm wrong but it seems you can use iptables to set rules
such that all web traffic (port 80 and 443 for example) can be directed
into one traffic management queue (queue discipline?) and all apt-get
traffic can be routed into another queue (depending on which tcp port it
uses) and so on. I plan to implement (try to implement) this myself soon.
