Is there a particular reason why periodic updates would not work?

Pseudocode:

VIP=1.2.3.4
DOMAIN=realservers.domain.com
while true; do
        sleep 10
        clear_ipvsadm $VIP
        for ip in $(dig +short $DOMAIN); do
                add_realserver $ip
        done
done

Is it a special modification? It may be better to dynamically update the
 VIP instead of a flush though.
