Often, an admin who owns the clusters does not own the DNS servers and often those DNS servers are not Microsoft servers.

So what? You put in a request for the DNS entry for the virtual IP and name, and that is all you need. You should never need more because your clients as well as the nodes themselves can all resolve the name. If you don't configure DNS properly, your clients will never be able to connect anyways.

Also, remember, the hosts file has the private interface addresses ONLY, not the public.

The heartbeat does not give a hoot about the host name of the other side. Host names are not used in heart beat communications.

Anyway, I think your argument doesn't hold any water, since we're talking about making MSCS as fault tolerant as possible but then you make it *depend* on DNS for proper operation (not access from clients, but even then, we've used IP addresses for 30 years when DNS goes down).

Kenny, it isn't high availability unless the clients can access the services.
