Been running software load balancers for over a decade. I started with LVS (Linux Virtual Server) now called ivps. Now we run HAProxy and we're looking Apache Traffic Server.
Some of the load balancers have even run BGP as called out in the OP. Nothing really fancy but enough to be interesting.
One of the coolest things I built was a Global Server Load Balancer to balance Load Balancers. We needed it initially to move data centers. It was built on top of PowerDNS and ketama hash.
