Hi,

add zone sections for the other domains, add zonefiles for .net and 
.org that contain a line like "www IN CNAME www.domain.com".

PS: I do not think it is "sane" to reserve domain names like that but 
some of my customers do that too. However I want this to be 
treated officially like domain grabbing. (I do not intend to offend 
someone)
