Good to hear.  The actual directory will likely be small in size (number of objects).
So it sounds like as long as we manage the number of agreements (2-3) per node then we may be okay.

Another quick question, I assume there is a programatic call that can be made to trigger replication push for a supplier.  True?

thanks,

Jason

That means 4 is the highest number of masters we've tested
exhaustively.  The protocol supports up to 2^32-2 masters, but you will
usually hit a practical limit in the number of replication agreements.  
Each repl. agreement runs a separate thread, so you will usually be
constrained by resources - available RAM, processors, etc.

The application will write the changes directly to each of the 10 masters?

Yes, it is possible.
