Exchange 2010 DAG replication across the internet

ok, so I've been reading and posted a question or two here, and now I have more.

When replicating DAGs across the internet, is it a requirement to have two NICs?  It seems I need a network NIC and a replication NIC.  

I ask because my Exchange servers are VMs.  I can of course add a second NIC, but I'm curious if the replication NIC is a requirement or a recommendation.

Thanks

Exchange 2010 doesn't use the concepts of public and private networks. These concepts are replaced with the concepts of MAPI networks and replication networks. Each DAG should contain one MAPI network and one or more replication networks.

ok, fair enough.  so I add a second virtual nic, put it on a diff network.  my next problem is my two exchange boxes are separated by 100 miles, they are behind their own firewalls, etc.  what's the next step in making one replicate to the other?

•Each Mailbox server in a DAG must be member servers in the same domain. Exchange 2010 is not supported on nodes that are also Active Directory servers or nodes that are members of different Active Directory domains.
