I think that the best way is the tdb-based combined with the first
method for messaging information exchange.
However, I suggest that is not smbd which make the communication with
other's nodes, but a
'tdblockd' daemon which replicate each modification between node (like
a super slurpd).
This alternative can permit to administrator to use a different
network for replication system.
A other advantage is that there are no change of smbd code for add
this task or thread.
LAN1 : 10/100 Mb for client purpose
LAN2 : 1Gb for backup and replication tasks.
