[CentOS] OT NIS Question

Hi People,

I have been been using a NIS setup that I inherited for some time now 
and my eventual goal is to replace it with LDAP.  But in the mean time I 
am looking at migrating some servers to new equipment and wondered if it 
is possible to have a single ypserv install servicing two NISDOMAINS?  
In this particular situation it would be a situation where for one 
domain the server would be a master and the other a slave.  My initial 
research can't find anyone doing something similar. So can anyone 
familiar with NIS advise as to whether what I am thinking of is plausible ?
