Operations Manager 2012 Resource Pools and multiple datacenters

We are planning the future installation of OM 2012 in our 2 main datacenters. 
1. We use a single management group across both datacenters for DR and operational purposes. 
2. We are looking for datacenter A to be our primary and contain the active DBs with 3 management servers there, and 3 in the datacenter B. 
3. Server agents in datacenter A will connect to A and servers in datacenter B will connect to management servers in B. 
4. A mirrored database server will exist in datacenter B for manual failover in a DR situation (using CNAMEs for the instances).
 
How should we handle Resource Pools in this scenario?  Should there be two separate pools (in addition to the automatic ones) or one spanning both datacenters?  If we use two separate pools, is there an effective way to direct user console sessions to connect to either resource pool's management servers (for example DNS round robin)?

Yes, I know this is an old post, I’m trying to clean up older posts that are unanswered.
Did you ever figure this out?
