You can tell icecast to bind to port 80 instead of 8000, but this may
require root privileges.

Or just use a D-NAT rule in what ever firewall your using..

I use the following rule for iptables/netfilter

iptables -t nat -A PREROUTING -i eth0 -p TCP --dport 80 -j DNAT --to

This has the effect of making it appear to the outside world that 
icecast is listening on both 80 and 8000, and is going to be a lot 
cheaper in terms of resources than proxying the connection.
