Release 2.0.13 will allow you to use dn-based selective subtree 
replication within ONE SINGLE database, so if this was the only 
requirement driving you towards back-meta, you may try to use 
this new feature.

You need to configure one single database:

	database ldbm
	# use the rightmost part of the naming context as database suffix
	suffix "dc=org"

and set the per-suffix replication in each replica:

	# use subtrees of the base naming context 
	# to enable selective replication
	# note: you may configure each slave to use
	# "dc=ncX,dc=org" as suffix, so you don't
	# need to recreate the common entry "dc=org"
	replica host=host1 suffix="dc=nc1,dc=org" ...
	replica host=host2 suffix="dc=nc2,dc=org" ...
	...
	replica host=hostX suffix="dc=ncX,dc=org" ...

But beware of this bug:

you'd better wait for 2.0.14
