You will need at least 3 ip addresses. One ip for each box and one 'floating' ip for the services (like http, smtp, pop, etc). Having the boxes at two separate ISPs is impossible since you won't be able to get them to fail over the 'floating' ip address, unless they really know what they are doing (both of them).
It's not a matter of the ISP's knowing what they are doing. It's that no ISP will announce a host route, x.x.x.x/32 into BGP. And if any ISP is retarded enough to announce it, no other ISP will accept it. So unless you're prepared to shift at minimum an entire class C, x.x.x.x/24, from one colo to the other any sort of IP sharing scheme is impossible.
