Question : Setting Up Geo Cluster Windows Server 2008 Exchange 2007

I am trying to setup a Geo Cluster using server 2008 for exchange 2007. Is this possible with the setup describe below

Node 1
Public NIC: 10.10.10.x
Heartbeat NIC: 10.20.10.x

Node 2
Public NIC: 10.30.10.x
Heartbeat NIC: 10.40.10.x

All of this communication will be between two regions over the public wan. Do you know of any sites explaining this type of setup? It seems that everything related to a Geo Cluster on the net talks about stretching the ips to the other region.

You're missing the subnet masks (so I can't determine if these IPs are in different subnets or not) - although stretch IPs shouldn't be needed in W2008.  Are you going to use CCR or a conventional cluster for this task?

See this link for more info on configuring CCR w/W2008:
