Hi all,
 
do you see an issue with the following replication topology:
 
 
S1 <----> S2 <---> S3 <---> S4
/\                                       /\
 |                                        |
\/                                       \/
S5 <----> S6 <---> S7 <---> S8
 
All connections are bi-directional (Multi-Master)
 
Thanks,
-Reinhard
