can be done at nearly no cost with two ALIX boards (depends on the load but often is enough) that are kept redundant with CARP on an interface, and then just do failover/loadbalancing with PFsense installed.
an alixboard has 3 interfaces, fits perfect:
1) Carp Sync 2) inside 3) outside

two redundant Layer4 switches with VRRP would help. You can deploy some expensive boxes like Alteon, or try building your own from open source. Actually two Cisco boxes with some tricky NAT would help too.
Basically you need to redirect the requests for a single public IP address into several private IP addresses in your datacenter.
