[JDEV] Server->Server Message

[David Waite]

This is my understanding:

Interactions change slightly, but the protocol is the same. Things like
karma are treated differently for server-server connections due to more
messages being sent. I believe the server can also cut the connection (it
does not need to be long-lived).

There is the dialback handshaking which uses DNS to validate the remote
server, since the local server doesn't have 'account information' to
'authenticate' the server with.

presence type="probe" is allowed for servers, to get current values of
presence to feed to a user (users cannot probe presence to prevent clients
which 'poll' presence every 30 seconds rather than caching the values
locally - polling does not scale.) I am unsure of the exact protocol for
this - for instance, if the server requires specifying the users in 'to'
and 'from' in order to validate the subscription on the remote side.

But other than that, pretty much the same thing, just more traffic.
