To quote DJB:

Don't use [CNAME] if there are any other records for [the fully  
qualified domain name]. Don't use [CNAME] for common aliases; use  
[the fully qualified domain name] instead. Remember the wise words of  
Inigo Montoya: ``You keep using CNAME records. I do not think they  
mean what you think they mean.''  (http://cr.yp.to/djbdns/tinydns- 
data.html)

The above record would be written like this in TinyDNS:

+athena.domain.com:192.168.1.1:3600

Not to start a war, but doesn't that look much easier?
