Why? This is conceptually the same as running a GossipRouter on a 
public, DNS-mapped, IP address...

The real challenge with cross-cloud clusters is (as you and I 
discovered) to bridge the non-public addresses of local cloud members 
with members running in different clouds.

Unless you make all members use public IP addresses, but that's not 
something that's typically advised in a cloud env.

Sure, should be simple. But - again - what's the goal? If 
discovery.etcd.io can be used as a public *permanent* discovery service, 
yes, cool
