That is not true! You can have multiple CNAME to one IP, but can only have
one IP to lookup one name. Only the named.rev is limited, not the
named.hosts.

I don't  know if it is a schame to name the news server others than
"news". So why use an alias name at all? Beside this, if the news server
really exist on your site, than it should get anyway a new machine  soon,
when the traffic starts ;-)

However if the question was if you can use other ones news server to say
it is yours, than you have the problem.
(I saw once an entry in named.hosts like:

news    CNAME    news.server.other_ISP.      (trailing dot!!!)

Worked perfect! You only find it, if you make a telnet news 119 and saved 
the small ISP a lot of GB harddisk. BTW, even after they have been bought 
from a big organization, they still use the other ones news server ;-( I 
just telnet them).
