Hi all, 
I have a pair of nagios servers in active/passive configuration, both of 
them are running also ndomod/ndo2db over a local MySQL database. 

I set up a little script which polls the db for host/service checks and 
pushes them to the backup (using NSCA). I think it could be easily done
for acknowledgments too, and NDOUtils/MySQL are easy enough to setup 
(and don't seem to have great performance impact), or you could 
parse nagios.dat and get the acknowledgments from there, then push them 
to the secondary server.  

Cheers, 
Giacomo
