Would it be more clever to take advantage of the fact that we have a

in the best interest to be able to load other NSS modules?
I think the lookupd should be able to link nss modules.  Oh how cool 
would it be if pam could do that as well...

LDAP itself can be configured to pass requests to other LDAP servers.
There's also a small issue with cache_timeout: if you have local 
cache_timeout of 30s and configure it to contact another instance of 
lookupd that also caches it for 30s, could the data get 1 minute stale?
just send the timeout information (like recursive DNS does).
