Rod,

For evaluation and testing, I have done this.  But NEVER
do this in production.  The entire Ingres transaction 
system (as well as Oracle's, Sybase's, Informix's) relies
on "knowing" when data has actually been written to a 
physical disk.  

With NFS, there is NO WAY to know when data is actually 
written to a disk.  You can put yourself in a situation
you cannot recover from.
