(I'm assuming you already use the XS headers module; otherwise that's  
an easy win).

I haven't tried it, but doesn't the Linux iptables have a "random"  
module?  If so then you should be able to redirect half the new  
connections to one port and the other half to the other.

If you use FreeBSD or OpenBSD then I imagine pf has a "random" thing,
