Very true. Till we have cluster mirroring this is obviously the worst idea. I was however under the impression that mirroring support was now available (maybe not for production?).
When cluster mirroring is ready this will help somewhat, but it's nowhere near the same thing as distributing the load over 20 machines and keeping it reliable.
