mainly more nodes.  multidatacenter is a plus. (I mainly use multidatacenter to do live migration, then storage migration on local dc storage).

Oh yes, that could be perfect !

What problem do you want to solve exactly? Only more nodes? Or nodes 
between physically distant data centers? 

An alternative plan would be to write a management tool which 
can deal with multiple (corosync) clusters. I always wanted such 
tool, and I guess it is not really hard to write one. 

Things like HA failover would still be restricted to a single 
corosync cluster. What do you think about this idea?
