Which dous not *imply* that you should use multiple A instead of
one A and multiple CNAMES "pointing to" that A

In fact when naming a resource maintained by another organisation
( I.e. you outsource your webserver to company Y but want
the world to connect to your webserver as www.myorganisation.dk then
a cname is the only sensitive way to do this.

My comment here is that a network where a double dns-resolution is 
the grain that breaks the camels back, then you certenly have 
problems. But not with DNS !!

If this concerns were widespread we should use ip4 addresses everywhere
and skip dns altogether.
