The only thing that doesn't make sense, then, is why all the other Spread
calls take just the mailbox, and not the private group name.  Is it the case
that when a single application makes multiple connections to Spread, the
mailboxes (and also private names) will have unique numbers, but that Spread
determines which application is making the call, to associate with the

That is perfectly normal.

The mailbox is just the file descriptor of the tcp (or unix socket)
connection to the Spread daemon. The access to private messages and the
'unique' name for each connection is the 'private group name' that is
returned in a result parameter of the SP_connect call. That name is made up
of the user name you passed to SP_connect and the name of the machine the
daemon is running on. It will always be unique amoung all current
connections to any of the daemons in the system.

Hope this makes sense,
