Yes, BGP must be supported by the upstream ISP in order to work. I'm an engineer at FatPipe Networks and we sell a Linux-based appliance that provides redundancy and load balancing without the use of BGP. And yes, we do it using DNS, but our box is intelligent in that it will detect line failures and change the way it answers DNS. The DNS runs on our box (we're running BIND).
