That should work fine.  The only problem might be the WINS 
registration.  The NT clients look for DOMAIN<1b> on the WINS 
server to locate the DC.

Also make sure that you copy

	- smb.conf
	- private/MACHINE.SID
	- private/smbpasswd

to the second machine.

Just to make sure, you are talking about only having one run at 
a time, simply being able to start the second up if the first DC \
crashes, correct?

PDC<->BDC integration is really the PDC<->BDC replication process.
The protocol which MS uses to do this is undocumented and needs
more study to implement.
