BGP isn't better.  You don't need BGP for multihoming.  My SF NANOG talk
was on exactly this topic.  If you get a little bit of PA space from each
provider, and run a multihomed server (or a whole pile of them) with the
"interface default" mods we made available, you don't need BGP at all.

ftp://ftp.vix.com/pub/vixie/ifdefault/ is the place to look for this.  I
just stuck a copy of my SF NANOG slides in there (SOB, please take note!)

Sure there is.  It's called "not fouling your own nest."  If you're not
using it, and it's too small to be routable by modern providers, then you
should give it back and let someone else try to aggregate it.
