slapd.conf on A:
-----
database    ldbm
suffix 
    "cn=rightHalf.."
replica     host=<B>
            "binddn=blah.."
            bindmethod=whatever ..
...

database    ldbm
suffix      "cn=leftHalf.."
replica     host=<C>
            "binddn=blah.."
            bindmethod=whatever ..
...
-----

works fine..

a slave without a master isn't a slave, i'd say.. but.. if you don't 
want to have a master, where exactly is your problem..? read that flat 
updatefile and add the changes to your appropriate ldapservers.. (that's 
what slurpd does too..) you also might want to write out your 
updatefiles in "replication-format" and let slurpd contact your 
"slaves".. might be worth a try..
