In a nutshell and very first of all, you need at least 2 internet connections. Those ISP must be willing to setup BGP peering between your routers and theirs. Once that agreement has been made, you need to get their AS Numbers and submit the ASN request located on ARIN's website (http://www.arin.net). After some paperwork and money exchanges, ARIN assigns you an AS number. At that point, you can configure the BGP peering. There's more details to it, but that's what I went through in a nutshell. ARIN has a pretty good flowchart of their process located at http://www.arin.net/education/asn_process/index.html

I believe the original poster was talking about the Internet, but I could be wrong.
Yes I am talking about the Internet, not an Intranet. Thanks for all your replies, especially Brian, they've helped me see more clearly what the options are. I'd already given up on Round Robin or any other kind of DNS 'solution' before I posted, after reading this: http://homepages.tesco.net./~J.deBoynePollard/FGA/dns-round-robin-is-use less.html
I don't think the difficulties and expense of getting an AS number and setting up BGP to work with our ISP will be worth it, but I'm not sure -
what steps exactly are involved in doing that?
