lateral NS delegation

[alexk at tugger.net]

Are there any inherent problems with a lateral NS delegation?  

Supposing that the root-servers are delegating 192.168.1.0/24 to my
nameservers via:

  1.168.192.in-addr.arpa.	IN NS	ns1.foo.com.

On ns1.foo.com, I have this conf entry:

  zone "1.168.192.in-addr.arpa" { type "master"; file "zonefile"; };

and the zonefile for 1.168.192.in-addr.arpa is this:

  @ IN SOA ns1.foo.com. hostmaster.foo.com. ( <SOA info snipped> )
  1.168.192.in-addr.arpa.	IN NS	ns1.otherfoo.com.

Is this a good method to delegate 1.168.192.in-addr.arpa to
ns1.otherfoo.com, or will there be a problem because it is a lateral
delegation?
