You can only control traffic that leaves an interface and you can't combine 2
interfaces. But with the imq device, you can redirect whatever-you-want
traffic to the 1 device. So you can redirect traffic that leaves eth0 and
eth1 to the same device, you can combine both interfaces.

No. But sometimes you need the imq device.

Good.

As long as you don't have more then 10^6 filter rules, you are fine :) You
should be more worry about active classes. I once created 5000 active
classes on a 486, 25Mhz, 8MB Ram and I was able to shape 10mbit without
remarkable delays.
