There was an interesting talk at the recent european BSD conference in 
Amsterdam, on NFS based NetBSD installations, using shared root 
filesystems. The paper can be had from:

In brief, the talk covered what could and could not be stored read-only, 
where to use MFS. It transpired that what couldn't be used read-only can 
simply be union-mounted with MFS filesystems, avoiding the wastage of 
conventional ram disks.

The author was somewhat coy about releasing the scripts he used, but the 
paper and presentation should provide you with a reasonable starting 
point to look at implementing your own system.
