nfs and automounter are an evil plan from sun to drive system
administrator insane :)
that said there is nothing better than that for sharing resources, and
if thet are correctly configured they work flawlessly.

i have a similar setup, where my frontend mail/web servers are hosted in
a dc, in order to secure communication between those i just did:
/etc/ipsec.conf
spdadd X.Y.W.1 X.Y.W.2 any -P in ipsec
esp/transport//require
ah/transport//require;
spdadd X.Y.W.1 X.Y.W.2 any -P in ipsec
esp/transport//require
ah/transport//require;
/etc/racoon/psk
X.Y.W.1 this_very_secret_string_you_no_guess
X.Y.W.2 this_very_secret_string_you_no_guess
/etc/shorewall/zones
loc ipsec mode=transport
/etc/shorewall/policy
fw loc ACCEPT
loc fw ACCEPT
net loc NONE
loc net NONE
now i am sure that each host cannot be spoofed or intercepted.
