You seem to be worried about IP blocks. You haven't let us 
know how you're going to detect failure and do the failover.

When both directors are side by side, you assume that the 
networking won't fail. When the directors are geographically 
separate, are you failing out because of network failure 
(OK, if so how are you going to detect failure) or node 
failure (poor use of failover, since you can't assume the 
network between the two nodes is up).

Once you've detected failure, do you have a plan for moving 
the IPs to the backup site?
