I wasn't on the list back when the thread I'm quoting from was active, 
so I don't believe there's any way to continue that thread. That said, 
quoting from the thread:

I'm attempting to set up a bidirectional/criss-cross multimaster setup, and I'm failing rather spectacularly.  One thing that my script does is - after
all the syncs are set up - and the one-time-copy is ostensibly finished (still working on eliminating 'ostensibly') - I then modify the
dbgroups to have both sides be 'source' - which is my understanding of what makes the setup master-master.

But when doing a criss-cross multimaster - do you retain the 'source target' designation? So both really *are* masters, but they treat the other as a slave?
Every time I try and fire up the remote server's bucardo with source/source, all hell breaks loose, and the syncs go "Bad".
