And there are load balancing solutions beyond DNS.  You can set up a
router-like box at a published IP address that does TCP port/address
rewriting to transparently spread inbound requests across a farm of internal
private IP addresses.  Cisco's LocalDirector
 http://www.cisco.com/warp/public/751/lodir/ ) does this.  I think it's just
a matter of time before somebody gets motivated enough to add the necessary
support to Linux's IP Masquerading code---it's most of the way there
already.
