The problem is both ISPs are small and have /24s from their providers. The /24s would be filtered by many, leading to only partial connectivity in the case of failure. (Partial connectivity is better than no connectivity, I guess...)
What I would advocate here - though it is probably less feasible in the North American context - is application level multihoming. For mail, backup MX'es for inbound, and smarthosts for outbound. For Web access, if the ISP operates a proxy cache for its customers, the customers' actual IP address becomes irrelevant. There has been some discussion in the Squid users' mailing list about this, and we (the Squid contributors) are looking into means and ways of making upstream switchover more transparent. Granted, running caches in our part of the world (across the Pacific from MAE-West) is a must for reasonable performance at reasonable cost.
