Whether this works depends on whether $qio or RMS is used to access the
mailbox, and that's a Powerhouse internal thing, not under your control.
It probably uses $qio.

What you could do is write a 3gl bridge or relay, to create the mailbox on the
local node, and open the remote mailbox using RMS, and just copy stuff between
the two. We used this technique for a while during our VAX->Alpha migration.

Using RMS, stuff like send/signal EOF, wait on send/receive/full may not work
the same over DECnet.
