Yes. You can find the needed info on www.lart.org and www.docum.org.
Basically, you have to add a cbq or htb root qdisc to your internet NIC, add
1 class that will contains all traffic and 2 other classes.
In case you use HTB :
root qdisc 128kbit
|- class rate = ceil = 128kbit
|- class 1 : rate = 64kbit, ceil = 128kbit
|- class 2 : rate = 64kbit, ceil = 128kbit
Use a filter (u32) to redirect the traffic from the hosts you will bound to
class 1 and all other traffic to class 2.
Class 1 and class 2 will always get 64 kbit and will use all bandwidth that's
not used by the other class.
Remember you can only shape outgoing bandwidth with this setup.
