I've built gluster systems that did the internal stuff over an IB network and did the external stuff over 10G..

I didn't even think about it and it just worked.

The idea that I am proposing would be to have every gluster peer have all private peer addresses in /etc/hosts, but the public addresses would be in DNS.  Clients would use DNS.

Of course I would have the usual scalability problems associated with relying in part on /etc/hosts, but knowing that in advance, we can take the proper precautions.
