[Samba] samba4 PDC to BDC file replication

Im looking for a nice setup like this.
with samba4 DC and DC replication. 
Samba 4 DC ( and RODC's ) and having multiple subnets and remote locations. 
using bind for dns. 
Integrations of Zarafa schema in AD. 
having other servers with nfs linked nfs v2 3 ( like to have v4 also ) 
I can make a nice howto, but im missing some knowledge and the caveats where to lookout for. 
Im going to use debian or ubuntu, depends. I like debian more, but my servers are Dell, 
and ubuntu is adviced by dell, because of bit better driver support
Looked a lot, and yes there's a lot out there but all snipets of what im looking for. 

I'll like a nice howto based on real world networks. 
Im working now on a howto and setup voor nagios3 with centreon on ubuntu ( and more) , without compiling. 
Only debs used, i can only do 1 howto at a time. For example this setup, first time took 8 hours.
Now im at about 90% of the setup, install time is now about 2.5 hours.. 
So, if someone is installing samba, please please, write down very step, failuere, success, and put it here.
Or on your website, let us all know what your doing, how and we learn all. 
And let us know why your choosing for a setup, this is i think most important. 
and yes i know this place.  ;-)  http://wiki.samba.org/index.php/Samba4  
And many thanks to the samba team for all support here.

Being a mirror it "should" keep the NTFS permissions set? 

I will try this out and report my findings.

Thanks Daniel, I did have a look at that option and it now I looked harder it is an excellent solution! 

Basically Glusterfs will replicate the file storage. 

Glusterfs looks straight forward enough to setup:
