This is apparently unsupported (it may work,
we are using geographically distant servers in a couple of realms,
but the network between the servers may not be flaky no matter what)

You are thinking in an "inappropriate" way. Clients interact with _realms_,
and internally pick servers to talk to. There is no user interface
to those internals and it is not supposed to be present.

A client will talk to some server(s) of the realm depending on what it thinks
of network bandwidth and of the servers' availability. That's it.
It will move "from server to server" when it feels for doing that,
it is totally Coda's internal business.

This is not as bad as it may seem, most often the clients pick the "nearest"
server, but you do not have any guarantee that they do so each time,
they don't.

Hope this helps to see what one may expect and what one shouldn't expect
from Coda.
