You can use the limit-match for this:

iptables -A FORWARD -s $LIMITED_HOST -d $DESTINATION \
-m state --state NEW -m limit --limit 10/hour -j ACCEPT

But you need some dropping/rejection rule later as well. And be sure that you
have some rule which allows ESTABLISHED connections, like

iptables -A FORWARD -m state --state RELATED,ESTABLISHED -j ACCEPT

But i think that's more a work for some application-proxy like Squid...
