e.g. enforced(!), centrally administered site-wide policy, incl. traffic
engineering inbound and outbound. With no way for hosts to make their
own decisions, nothing to (re)configure, no DNS complexity, no wastage
of bandwidth for keepalive, no communication setup delays (the slow DSL
line have already high latency, don't want to add anything to that) etc.

I can't see any, as it's a host multihoming solution, not a site
multihoming solution. The things I'm primarily missing (aside "keep it
simple on the host end, they don't even get TCP right") are site
multihoming features that you cannot sanely implement on hosts. But
I'm happy to be proven wrong. :-)


Best regards,
Daniel
