Please don't confuse "I need more than one pipe into the internet" with "my organization must place its prefixes into the default free zone".
It is possible to effectively use multiple pipes into many ISPs without the cost to all of us that introducing your prefix into the DFZ has.
I am all ears as to how you propose I achieve provider independence without introducing my prefix(es) into the DFZ. eg, say I am connected to two upstreams, I would like to still continue reachability with the global net in case of failure of one of the upstreams (as wide failure), or a failure of an upstream POP (which happens to be the only one in my LATA) from one of the providers. /vijay

Take prefixes from both providers and use them. Route your egress traffic appropriately. My point wasn't that "there is no need to BGP multihome", but that many seem to see this as the only way of achieving use of multiple providers worth of pipe. There are other alternatives, depending on your application.
