Hi

there r couple things u can do:
1.  every rule in iptables counts bytes of data which went through it. u 
can look at the counters by using command:
iptables -L -v
or maybe more specific for FORWARD chain: iptables -L FORWARD -v

u can place a specific counter for one host:
/sbin/iptables -A FORWARD -j ACCEPT -i eth0 -m state --state ESTABLISHED 
-d 192.168.0.19 --set-counters 0 0

2. use specialized netfilter addons (patch-o-matic) for counting and 
possibly doing what ever u want with leechers. the ones u can use are 
from BASE repository: QUOTA and from EXTRA repository connbytes. the web 
site is of course www.iptabless.org
