Aggregate speed. However, the shaper fairly limits each connection (SFQ) when
the total limit is reached.

Yes, you can, per IP address. But you have to enter it manually in
/etc/network/ifup.local script.
Here is an example script, which sets traffic limit on an IP address:
====
#!/bin/sh
# Function to set HTB/SFQ shaper with fixed bandwidth on an IP address
set_shaper() {
IP=$1
SPEED=$2
ID=$3
tc class add dev eth0 parent 1:1 classid 1:$ID htb rate $SPEED ceil $SPEED
tc qdisc add dev eth0 parent 1:$ID handle $ID: sfq perturb 10
tc filter add dev eth0 protocol ip parent 1:0 prio 1 u32 match ip dst $IP/32
flowid 1:$ID
tc class add dev netcs0 parent 1:1 classid 1:$ID htb rate $SPEED ceil $SPEED
tc qdisc add dev netcs0 parent 1:$ID handle $ID: sfq perturb 10
tc filter add dev netcs0 protocol ip parent 1:0 prio 1 u32 match ip src
$IP/32 flowid 1:$ID
}
# ID should be a unique value >= 100
set_shaper IP_ADDRESS_HERE 128kbit 100
set_shaper ANOTHER_IP_ADDRESS 256kbit 101
===
A more complete example script would be included in the next release.
