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
