You could do that.  However, since you only have two servers there's  
no practical reason to distribute the perlbal load anyway.  I would  
setup perlbal on both boxes and just have wackamole move your public  
IP between the two.

If you need to bind to specific IPs (rather than just *:80) you can  
on Linux allow processes to bind to not-local IP addresses with

echo 1 > /proc/sys/net/ipv4/ip_nonlocal_bind

or the similar sysctl switch.
